A mobile agent offers discrete advantage both in facilitating better transmission as well as controlling the traffic load in Mobile Adhoc Network (MANET). Hence, such forms of network offers maximized dependencies on mobile agents in terms of its trust worthiness. At present, there are various work being carried out towards resisting security breach in MANET; however approaches using mobile agent based mechanism is few to found. Therefore, the proposed system introduces a novel mathematical model where an extensive decision making system has been constructed for identifying the malicious intention of mobile agents in case they go rogues. By adopting multi-tier communication policy and fairness concept, the proposed system offers the capability to resist any form of malicious activity of mobile agent without even presence of any apriori information of adversary. The outcome shows proposed system outshines existing security scheme in MANET.

AUTHENTICATION USING TRUST TO DETECT MISBEHAVING NODES IN MOBILE AD HOC NETWO...IJNSA Journal
Providing security in Mobile Ad Hoc Network is crucial problem due to its open shared wireless medium,
multi-hop and dynamic nature, constrained resources, lack of administration and cooperation.
Traditionally routing protocols are designed to cope with routing operation but in practice they may be
affected by misbehaving nodes so that they try to disturb the normal routing operations by launching
different attacks with the intention to minimize or collapse the overall network performance. Therefore
detecting a trusted node means ensuring authentication and securing routing can be expected. In this
article we have proposed a Trust and Q-learning based Security (TQS) model to detect the misbehaving
nodes over Ad Hoc On Demand Distance-Vector (AODV) routing protocol. Here we avoid the misbehaving
nodes by calculating an aggregated reward, based on the Q-learning mechanism by using their historical
forwarding and responding behaviour by the way misbehaving nodes can be isolated.
USING A DEEP UNDERSTANDING OF NETWORK ACTIVITIES FOR SECURITY EVENT MANAGEMENTIJNSA Journal
With the growing deployment of host-based and network-based intrusion detection systems in increasingly
large and complex communication networks, managing low-level alerts from these systems becomes
critically important. Probes of multiple distributed firewalls (FWs), intrusion detection systems (IDSs) or
intrusion prevention systems (IPSs) are collected throughout a monitored network such that large series of
alerts (alert streams) need to be fused. An alert indicates an abnormal behavior, which could potentially be
a sign for an ongoing cyber attack. Unfortunately, in a real data communication network, administrators
cannot manage the large number of alerts occurring per second, in particular since most alerts are false
positives. Hence, an emerging track of security research has focused on alert correlation to better identify
true positive and false positive. To achieve this goal we introduce Mission Oriented Network Analysis
(MONA). This method builds on data correlation to derive network dependencies and manage security
events by linking incoming alerts to network dependencies.
DESIGN AND IMPLEMENTATION OF THE ADVANCED CLOUD PRIVACY THREAT MODELING IJNSA Journal
Privacy-preservation for sensitive data has become a challenging issue in cloud computing. Threat

A mobile Ad-hoc network (MANET) is an impulsive network that can be recognized with no predetermined infrastructure. To achieve safe path selection cryptographic key exchange was implemented mostly in turn of huge computational cost. Confidence based coordination in MANET focuses on routing challenges created by selfish nodes, as energy utilization & time factor are key issues in this aspect. The present protocol is focused on fuzzy optimization-based node confidence estimation and path selection with minimum energy utilization. The node with maximum confidence value will give high priority to include in the path for transmission. In the implemented protocol to build a novel confidence-based model multidimensional factors like confidence value, link cost, degree of node and node energy are included as decision-making factors. The proposed protocol CLBNSRM estimates confidence level in four steps to decide a trustworthiness of neighboring node. To estimate the efficiency of the present confidence model various protocols are compared by using attributes like the number of nodes, node speed, malicious node variation, etc. Moreover, different parameters like Packet delivery ratio, Throughput, Residual energy, and Packet dropped are considered with these attribute variations. Experimental results indicate that PDR and Throughput increase although in presence of malicious nodes, along with the utilization of minimal energy. Statistical analysis is carried out for mathematical modeling. This analysis shows that a linear model of an implemented protocol is better than compared protocol with all the aspects.
Delay Tolerant Networks (DTNs) have high end-to-end latency, which is often faces disconnection, and unreliable wireless connections.

The proposed dynamic trust management protocol uses a dynamic threshold updating which overcomes the problems with time changing dynamic characteristics by dynamically updating the criteria in response to changing network conditions. This reduces overheads and increases the efficient use of routing network even in conditions change. Also the dynamic threshold update reduces the false detection probability of the malicious nodes. To show the effectiveness of the proposed system, a detailed simulation in the presence of selfish and malicious nodes is performed with ONE simulator.

Internet of Things (IoT) offers reliable and seamless communication for the heterogeneous dynamic lowpower and lossy network (LLNs).

An efficient approach for secured communication in wireless sensor networks IJECEIAES
Wireless sensor network (WSN) have limited bandwidth, low computational functions, energy constraints. Inspite of these constraints, WSN is useful where communication happens without infrastructure support. The main concern of WSN is the security as the sensor nodes may be attacked and information may be hacked. Security of WSN should have the capability to ensure that the message received was sent by the particular sent node and not modified during transmission. WSN applications require lightweight and strong authentication mechanisms for obtaining data from unprivileged users. In wireless sensor networks, authentication is the effective method to stop unauthorized and undisrupted communication service. In order to strengthen the authenticated communication, several researchers have developed mechanisms. Some of the techniques work with identifying the attacked node or detecting injected bogus message in the network. Encryption and decryption are the popular methods of providing the security. These are based on either public-key or symmetric-key cryptosystems.Many of the existing solutions have limitations in communication and computational expertise. Also, the existing mechanisms lack in providing strength and scalability of the network. In order address these issues; a polynomial based method was introduced in recent days. Key distribution is a significant aspect in key management in WSNs. The simplest method of distribution of key is by hand which was used in the days of couriers. Now a day, most distribution of keys is done automatically. The automatic distribution of keys is essential and convenient in networks that require two parties to transmit their security keys in the same communication medium. In this work, a new type of key exchange mechanism is proposed. The proposed method for authentication among sensor nodes proves to be promising as per the simulation results. The nodes which are unknown to each other setup a private however arbitrary key for the symmetric key cryptosystem.

Modelling of A Trust and Reputation Model in Wireless Networksijeei-iaes
Security is the major challenge for Wireless Sensor Networks (WSNs). The sensor nodes are deployed in non controlled environment, facing the danger of information leakage, adversary attacks and other threats. Trust and Reputation models are solutions for this problem and to identify malicious, selfish and compromised nodes. This paper aims to evaluate varying collusion effect with respect to static (SW), dynamic (DW), static with collusion (SWC), dynamic with collusion (DWC) and oscillating wireless sensor networks to derive the joint resultant of Eigen Trust Model. An attempt has been made for the same by comparing aforementioned networks that are purely dedicated to protect the WSNs from adversary attacks and maintain the security issues. The comparison has been made with respect to accuracy and path length and founded that, collusion for wireless sensor networks seems intractable with the static and dynamic WSNs when varied with specified number of fraudulent nodes in the scenario. Additionally, it consumes more energy and resources in oscillating and collusive environments.

ABSTRACT
In this paper, we propose a routing protocol that is based on securing the routing information from
unauthorized users. Even though routing protocols of this category are already proposed, they are not
efficient, in the sense that, they use the same kind of encryption algorithms (mostly high level) for every
Bit of routing information they pass from one intermediate node to another in the routing path. The
proposed mechanism is evaluated against selected alternative trust schemes, with the results showing that
our proposal achieves its goals.Our research aims at providing a secure and distributed
authentication service in the ad hoc networks.

n-Tier Modelling of Robust Key management for Secure Data Aggregation in Wire...IJECEIAES
Security problems in Wireless Sensor Network (WSN) have been researched from more than a decade. There are various security approaches being evolving towards resisting various forms of attack using different methodologies. After reviewing the existing security approaches, it can be concluded that such security approaches are highly attack-specific and doesnt address various associated issues in WSN. It is essential for security approach to be computationally lightweight. Therefore, this paper presents a novel analytical modelling that is based on n-tier approach with a target to generate an optimized secret key that could ensure higher degree of security during the process of data aggregation in WSN. The study outcome shows that proposed system is computationally lightweight with good performance on reduced delay and reduced energy consumption. It also exhibits enhanced response time and good data delivery performance to balance the need of security and data forwarding performance in WSN.
Detecting Misbehaving and Selfish Nodes in the Network using Watchdog MechanismINFOGAIN PUBLICATION
The nodes in a wireless network may misbehave at times. This misbehavior needs to be monitored in order to avoid sudden failure of network. The watch dog mechanism has been sufficiently studied to address the issue of malice node detection, in Mobile Adhoc Networks (MANETs). A Collaborative Contact based Watchdog (CoCoWa) is collaborated with information diffusion in the proposed work. This combination strategy analyses all the nodes in a network and provides the information update regarding the selfishness of the specific nodes to other nodes and routing protocols to enable performance oriented transmission. Once the selfish node is detected by the watch dog, it is marked as selfishness positive node else the node is marked as negative selfish node. For enabling this fool proof approach, true neighbors, fake neighbors, their probability of relationships with each other is analyzed. The evaluation of the viability of the proposed work is made in terms of detection efficiency, detection accuracy of both malicious and selfish nodes. Apart from these, the strategy is proved to be simple yet effective.
Improving Network Security in MANETS using IEEACKijsrd.com
This document discusses improving network security in mobile ad hoc networks (MANETs) using an improved version of the EAACK intrusion detection system called IEEACK. IEEACK aims to address some of the weaknesses of EAACK related to link breakage, malicious sources, and partial packet dropping. The document describes the components of IEEACK, including ACK, S-ACK, MRA, digital signatures, and a new trust-based quality of service model. Simulation results show that IEEACK can prevent attacks from malicious nodes and improve security performance metrics like packet delivery ratio and detection of malicious nodes.
The underlying fabric for communication among intelligent
agents will in many cases be provided by telecommunication
networks. But telecommunication networks have been seen as
a natural domain for the investigation and application of
intelligent agents’ technology as it emerged from the area of
Distributed Artificial Intelligence (DAI). Telecommunication
network administrations are vast organizations dedicated to
operating and managing networks with broad functional
segmentations: telephone network outside plant, switching and
transmission plants, public network, all supporting different
layers of specialized customer or service networks. These
networks are organized into multiple physical and logical
layers built with large quantities of repeated network elements
and sub network structures. All these elements need to be
configured, monitored, and controlled. In the future, this will
preferably be done by automated operation support systems
and without substantial human intervention.
A Wireless Sensor Network is a multiple collection of large number of sensor nodes. These sensor nodes are used to collect the information from the surroundings and pass it to the base station. Data Aggregation is an important technique to achieve power resource effectively in the sensor network. Because sensor node has limited battery power so data aggregation techniques have been proposed for WSN. The data from the multiple sensor nodes are aggregated is usually performed by averaging method. The aggregated data are stored into header aggregator node and it is highly susceptible to attacks. To address this security issue, Iterative Filtering algorithms are used to monitor sensor nodes and provide great promise by detecting vulnerable errors. For transferring aggregator data from aggregated node to base station, this paper introduces Cryptography and Random Key Generation technique. We use encryption technique for original message and simultaneously create a key for that encrypted message. That generated key and encrypted message will be sent to the receiver through the possible paths where the hackers cannot hack the original message.
A COMBINATION OF TEMPORAL SEQUENCE LEARNING AND DATA DESCRIPTION FOR ANOMALYB...IJNSA Journal
Through continuous observation and modelling of normal behavior in networks, Anomaly-based Network Intrusion Detection System (A-NIDS) offers a way to find possible threats via deviation from the normal model. The analysis of network traffic based on time series model has the advantage of exploiting the relationship between packages within network traffic and observing trends of behaviors over a period of time. It will generate new sequences with good features that support anomaly detection in network traffic and provide the ability to detect new attacks. Besides, an anomaly detection technique, which focuses on the normal data and aims to build a description of it, will be an effective technique for anomaly detection in imbalanced data. In this paper, we propose a combination model of Long Short Term Memory (LSTM) architecture for processing time series and a data description Support Vector Data Description (SVDD) for anomaly detection in A-NIDS to obtain the advantages of them. This model helps parameters in LSTM and SVDD are jointly trained with joint optimization method. Our experimental results with KDD99 dataset show that the proposed combined model obtains high performance in intrusion detection, especially DoS and Probe attacks with 98.0% and 99.8%, respectively.
Internet of things-based photovoltaics parameter monitoring system using Node...IJECEIAES
The use of the internet of things (IoT) in solar photovoltaic (PV) systems is a critical feature for remote monitoring, supervising, and performance evaluation. Furthermore, it improves the long-term viability, consistency, efficiency, and system maintenance of energy production. However, previous researchers' proposed PV monitoring systems are relatively complex and expensive. Furthermore, the existing systems do not have any backup data, which means that the acquired data could be lost if the network connection fails. This paper presents a simple and low-cost IoT-based PV parameter monitoring system, with additional backup data stored on a microSD card. A NodeMCU ESP8266 development board is chosen as the main controller because it is a system-on-chip (SOC) microcontroller with integrated Wi-Fi and low-power support, all in one chip to reduce the cost of the proposed system. The solar irradiance, ambient temperature, PV output voltage and PV output current, are measured with photo-diodes, DHT22, impedance dividers and ACS712. While, the PV output power is a product of the PV voltage and PV current. ThingSpeak, an opensource software, is used as a cloud database and data monitoring tool in the form of interactive graphics. The results showed that the system was designed to be highly accurate, reliable, simple to use, and low-cost.
Constructing a predictive model for an intelligent network intrusion detectionAlebachew Chiche
This document presents a study that constructs a predictive model for network intrusion detection using data mining techniques. The study uses the KDD Cup 99 intrusion detection dataset to build classification models using J48 decision tree, JRip rule induction, Naive Bayes, and multilayer perceptron algorithms. The J48 decision tree algorithm achieved the highest accuracy of 99.91% and was selected to build the predictive model. This model was then integrated with a knowledge-based system to build an intelligent network intrusion detection system capable of automatically detecting network attacks, mapping detections to attack categories, and updating the training data over time. Experimental evaluation found the integrated system achieved 91.43% accuracy and 83% user acceptance in detecting network intrusions
Now a day the technology is improving day by day. The wired network has been changed to wireless network. There are many advantages of wireless network over wired network. One of the main advantage is we can walk around freely in a network area and accesses internet. Security is one of the challenging issues.

Distributed Packet Filtering Firewall for Enhanced Security In Mobile Ad-Hoc ...IJERA Editor
The nodes in MANET are free to move in a limited grid layout without the presence of vision of the superior
authority or administration. The nodes in network are free to move in any other network at any time. That means
the nodes are join or leave the network at any instant, that's why the security is the major issue in MANET.
Routing protocols are not able to handle the malicious activities of attacker because their function is to provide
the path in between sender to receiver and route data from the path which is selected for transferring information.
This paper proposed the distributed security scheme for providing reliable path and secure communication. The
proposed bloom filtering technique is not only filtering the unwanted infected packets of routing attacker. It's
also recovered the modified data and protects IP modification with the help of new route establishment
mechanism. The proposed bloom filter is provides the secure communication and stop the attacker infection. The
Bloom filter removes the IP modified packets that shows the presence of malicious routing attacker in dynamic
network. The normal routing performance and proposed bloom filter is almost equivalent. The performance of
network is measured through performance metrics and proposed distributed security scheme provides better
performance.
A COOPERATIVE LOCALIZATION METHOD BASED ON V2I COMMUNICATION AND DISTANCE INF...IJCNCJournal
Relative positions are recent solutions to overcome the limited accuracy of GPS in urban environment.
Vehicle positions obtained using V2I communication are more accurate because the known roadside unit
(RSU) locations help predict errors in measurements over time. The accuracy of vehicle positions depends
more on the number of RSUs; however, the high installation cost limits the use of this approach. It also
depends on nonlinear localization nature. They were neglected in several research papers. In these studies,
the accumulated errors increased with time due to the linearity localization problem. In the present study,
a cooperative localization method based on V2I communication and distance information in vehicular
networks is proposed for improving the estimates of vehicles’ initial positions. This method assumes that
the virtual RSUs based on mobility measurements help reduce installation costs and facilitate in handling
fault environments. The extended Kalman filter algorithm is a well-known estimator in nonlinear problem,
but it requires well initial vehicle position vector and adaptive noise in measurements. Using the proposed
method, vehicles’ initial positions can be estimated accurately. The experimental results confirm that the
proposed method has superior accuracy than existing methods, giving a root mean square error of
approximately 1 m. In addition, it is shown that virtual RSUs can assist in estimating initial positions in
fault environments.
IRJET - Security and Privacy by IDS SystemIRJET Journal
This document summarizes a research paper that proposes an intrusion detection system (IDS) to detect spoofing attacks in wireless sensor networks. The IDS monitors node activities and detects if a node is behaving abnormally or attacking the network. If an attack is detected, the IDS sends an alarm message to the affected node to isolate the attacker. The paper simulates this approach using OTCL language in Network Simulator 2 on Linux. The results show the IDS can efficiently detect spoofing attackers in the wireless network.
A trust based secure access control using authentication mechanism for intero...IJECEIAES
The internet of things (IoT) is a revolutionary innovation in many aspects of our society including interactions, financial activity, and global security such as the military and battlefield internet. Due to the limited energy and processing capacity of network devices, security, energy consumption, compatibility, and device heterogeneity are the long-term IoT problems. As a result, energy and security are critical for data transmission across edge and IoT networks. Existing IoT interoperability techniques need more computation time, have unreliable authentication mechanisms that break easily, lose data easily, and have low confidentiality. In this paper, a key agreement protocol-based authentication mechanism for IoT devices is offered as a solution to this issue. This system makes use of information exchange, which must be secured to prevent access by unauthorized users. Using a compact contiki/cooja simulator, the performance and design of the suggested framework are validated. The simulation findings are evaluated based on detection of malicious nodes after 60 minutes of simulation.

An efficient security framework for intrusion detection and prevention in int...IJECEIAES
Over the past few years, the internet of things (IoT) has advanced to connect billions of smart devices to improve quality of life. However, anomalies or malicious intrusions pose several security loopholes, leading to performance degradation and threat to data security in IoT operations. Thereby, IoT security systems must keep an eye on and restrict unwanted events from occurring in the IoT network. Recently, various technical solutions based on machine learning (ML) models have been derived towards identifying and restricting unwanted events in IoT. However, most ML-based approaches are prone to miss-classification due to inappropriate feature selection. Additionally, most ML approaches applied to intrusion detection and prevention consider supervised learning, which requires a large amount of labeled data to be trained. Consequently, such complex datasets are impossible to source in a large network like IoT. To address this problem, this proposed study introduces an efficient learning mechanism to strengthen the IoT security aspects. The proposed algorithm incorporates supervised and unsupervised approaches to improve the learning models for intrusion detection and mitigation. Compared with the related works, the experimental outcome shows that the model performs well in a benchmark dataset. It accomplishes an improved detection accuracy of approximately 99.21%.

An efficient approach for secured communication in wireless sensor networks IJECEIAES
Wireless sensor network (WSN) have limited bandwidth, low computational functions, energy constraints. Inspite of these constraints, WSN is useful where communication happens without infrastructure support. The main concern of WSN is the security as the sensor nodes may be attacked and information may be hacked. Security of WSN should have the capability to ensure that the message received was sent by the particular sent node and not modified during transmission. WSN applications require lightweight and strong authentication mechanisms for obtaining data from unprivileged users. In wireless sensor networks, authentication is the effective method to stop unauthorized and undisrupted communication service. In order to strengthen the authenticated communication, several researchers have developed mechanisms. Some of the techniques work with identifying the attacked node or detecting injected bogus message in the network. Encryption and decryption are the popular methods of providing the security. These are based on either public-key or symmetric-key cryptosystems.Many of the existing solutions have limitations in communication and computational expertise. Also, the existing mechanisms lack in providing strength and scalability of the network. In order address these issues; a polynomial based method was introduced in recent days. Key distribution is a significant aspect in key management in WSNs. The simplest method of distribution of key is by hand which was used in the days of couriers. Now a day, most distribution of keys is done automatically. The automatic distribution of keys is essential and convenient in networks that require two parties to transmit their security keys in the same communication medium. In this work, a new type of key exchange mechanism is proposed. The proposed method for authentication among sensor nodes proves to be promising as per the simulation results. The nodes which are unknown to each other setup a private however arbitrary key for the symmetric key cryptosystem.

Modelling of A Trust and Reputation Model in Wireless Networksijeei-iaes
Security is the major challenge for Wireless Sensor Networks (WSNs). The sensor nodes are deployed in non controlled environment, facing the danger of information leakage, adversary attacks and other threats. Trust and Reputation models are solutions for this problem and to identify malicious, selfish and compromised nodes. This paper aims to evaluate varying collusion effect with respect to static (SW), dynamic (DW), static with collusion (SWC), dynamic with collusion (DWC) and oscillating wireless sensor networks to derive the joint resultant of Eigen Trust Model. An attempt has been made for the same by comparing aforementioned networks that are purely dedicated to protect the WSNs from adversary attacks and maintain the security issues. The comparison has been made with respect to accuracy and path length and founded that, collusion for wireless sensor networks seems intractable with the static and dynamic WSNs when varied with specified number of fraudulent nodes in the scenario. Additionally, it consumes more energy and resources in oscillating and collusive environments.

ABSTRACT
In this paper, we propose a routing protocol that is based on securing the routing information from
unauthorized users. Even though routing protocols of this category are already proposed, they are not
efficient, in the sense that, they use the same kind of encryption algorithms (mostly high level) for every
Bit of routing information they pass from one intermediate node to another in the routing path. The
proposed mechanism is evaluated against selected alternative trust schemes, with the results showing that
our proposal achieves its goals.Our research aims at providing a secure and distributed
authentication service in the ad hoc networks.

n-Tier Modelling of Robust Key management for Secure Data Aggregation in Wire...IJECEIAES
Security problems in Wireless Sensor Network (WSN) have been researched from more than a decade. There are various security approaches being evolving towards resisting various forms of attack using different methodologies. After reviewing the existing security approaches, it can be concluded that such security approaches are highly attack-specific and doesnt address various associated issues in WSN. It is essential for security approach to be computationally lightweight. Therefore, this paper presents a novel analytical modelling that is based on n-tier approach with a target to generate an optimized secret key that could ensure higher degree of security during the process of data aggregation in WSN. The study outcome shows that proposed system is computationally lightweight with good performance on reduced delay and reduced energy consumption. It also exhibits enhanced response time and good data delivery performance to balance the need of security and data forwarding performance in WSN.
Detecting Misbehaving and Selfish Nodes in the Network using Watchdog MechanismINFOGAIN PUBLICATION
The nodes in a wireless network may misbehave at times. This misbehavior needs to be monitored in order to avoid sudden failure of network. The watch dog mechanism has been sufficiently studied to address the issue of malice node detection, in Mobile Adhoc Networks (MANETs). A Collaborative Contact based Watchdog (CoCoWa) is collaborated with information diffusion in the proposed work. This combination strategy analyses all the nodes in a network and provides the information update regarding the selfishness of the specific nodes to other nodes and routing protocols to enable performance oriented transmission. Once the selfish node is detected by the watch dog, it is marked as selfishness positive node else the node is marked as negative selfish node. For enabling this fool proof approach, true neighbors, fake neighbors, their probability of relationships with each other is analyzed. The evaluation of the viability of the proposed work is made in terms of detection efficiency, detection accuracy of both malicious and selfish nodes. Apart from these, the strategy is proved to be simple yet effective.
Improving Network Security in MANETS using IEEACKijsrd.com
This document discusses improving network security in mobile ad hoc networks (MANETs) using an improved version of the EAACK intrusion detection system called IEEACK. IEEACK aims to address some of the weaknesses of EAACK related to link breakage, malicious sources, and partial packet dropping. The document describes the components of IEEACK, including ACK, S-ACK, MRA, digital signatures, and a new trust-based quality of service model. Simulation results show that IEEACK can prevent attacks from malicious nodes and improve security performance metrics like packet delivery ratio and detection of malicious nodes.
The underlying fabric for communication among intelligent
agents will in many cases be provided by telecommunication
networks. But telecommunication networks have been seen as
a natural domain for the investigation and application of
intelligent agents’ technology as it emerged from the area of
Distributed Artificial Intelligence (DAI). Telecommunication
network administrations are vast organizations dedicated to
operating and managing networks with broad functional
segmentations: telephone network outside plant, switching and
transmission plants, public network, all supporting different
layers of specialized customer or service networks. These
networks are organized into multiple physical and logical
layers built with large quantities of repeated network elements
and sub network structures. All these elements need to be
configured, monitored, and controlled. In the future, this will
preferably be done by automated operation support systems
and without substantial human intervention.
A Wireless Sensor Network is a multiple collection of large number of sensor nodes. These sensor nodes are used to collect the information from the surroundings and pass it to the base station. Data Aggregation is an important technique to achieve power resource effectively in the sensor network. Because sensor node has limited battery power so data aggregation techniques have been proposed for WSN. The data from the multiple sensor nodes are aggregated is usually performed by averaging method. The aggregated data are stored into header aggregator node and it is highly susceptible to attacks. To address this security issue, Iterative Filtering algorithms are used to monitor sensor nodes and provide great promise by detecting vulnerable errors. For transferring aggregator data from aggregated node to base station, this paper introduces Cryptography and Random Key Generation technique. We use encryption technique for original message and simultaneously create a key for that encrypted message. That generated key and encrypted message will be sent to the receiver through the possible paths where the hackers cannot hack the original message.
A COMBINATION OF TEMPORAL SEQUENCE LEARNING AND DATA DESCRIPTION FOR ANOMALYB...IJNSA Journal
Through continuous observation and modelling of normal behavior in networks, Anomaly-based Network Intrusion Detection System (A-NIDS) offers a way to find possible threats via deviation from the normal model. The analysis of network traffic based on time series model has the advantage of exploiting the relationship between packages within network traffic and observing trends of behaviors over a period of time. It will generate new sequences with good features that support anomaly detection in network traffic and provide the ability to detect new attacks. Besides, an anomaly detection technique, which focuses on the normal data and aims to build a description of it, will be an effective technique for anomaly detection in imbalanced data. In this paper, we propose a combination model of Long Short Term Memory (LSTM) architecture for processing time series and a data description Support Vector Data Description (SVDD) for anomaly detection in A-NIDS to obtain the advantages of them. This model helps parameters in LSTM and SVDD are jointly trained with joint optimization method. Our experimental results with KDD99 dataset show that the proposed combined model obtains high performance in intrusion detection, especially DoS and Probe attacks with 98.0% and 99.8%, respectively.
Internet of things-based photovoltaics parameter monitoring system using Node...IJECEIAES
The use of the internet of things (IoT) in solar photovoltaic (PV) systems is a critical feature for remote monitoring, supervising, and performance evaluation. Furthermore, it improves the long-term viability, consistency, efficiency, and system maintenance of energy production. However, previous researchers' proposed PV monitoring systems are relatively complex and expensive. Furthermore, the existing systems do not have any backup data, which means that the acquired data could be lost if the network connection fails. This paper presents a simple and low-cost IoT-based PV parameter monitoring system, with additional backup data stored on a microSD card. A NodeMCU ESP8266 development board is chosen as the main controller because it is a system-on-chip (SOC) microcontroller with integrated Wi-Fi and low-power support, all in one chip to reduce the cost of the proposed system. The solar irradiance, ambient temperature, PV output voltage and PV output current, are measured with photo-diodes, DHT22, impedance dividers and ACS712. While, the PV output power is a product of the PV voltage and PV current. ThingSpeak, an opensource software, is used as a cloud database and data monitoring tool in the form of interactive graphics. The results showed that the system was designed to be highly accurate, reliable, simple to use, and low-cost.

Experimental evaluation found the integrated system achieved 91.43% accuracy and 83% user acceptance in detecting network intrusions
Now a day the technology is improving day by day. The wired network has been changed to wireless network. There are many advantages of wireless network over wired network. One of the main advantage is we can walk around freely in a network area and accesses internet. Security is one of the challenging issues.

Distributed Packet Filtering Firewall for Enhanced Security In Mobile Ad-Hoc ...IJERA Editor
The nodes in MANET are free to move in a limited grid layout without the presence of vision of the superior
authority or administration. The nodes in network are free to move in any other network at any time. That means
the nodes are join or leave the network at any instant, that's why the security is the major issue in MANET.
Routing protocols are not able to handle the malicious activities of attacker because their function is to provide
the path in between sender to receiver and route data from the path which is selected for transferring information.
This paper proposed the distributed security scheme for providing reliable path and secure communication. The
proposed bloom filtering technique is not only filtering the unwanted infected packets of routing attacker. It's
also recovered the modified data and protects IP modification with the help of new route establishment
mechanism. The proposed bloom filter is provides the secure communication and stop the attacker infection. The
Bloom filter removes the IP modified packets that shows the presence of malicious routing attacker in dynamic
network. The normal routing performance and proposed bloom filter is almost equivalent. The performance of
network is measured through performance metrics and proposed distributed security scheme provides better
performance.
A COOPERATIVE LOCALIZATION METHOD BASED ON V2I COMMUNICATION AND DISTANCE INF...IJCNCJournal
Relative positions are recent solutions to overcome the limited accuracy of GPS in urban environment.
Vehicle positions obtained using V2I communication are more accurate because the known roadside unit
(RSU) locations help predict errors in measurements over time. The accuracy of vehicle positions depends
more on the number of RSUs; however, the high installation cost limits the use of this approach. It also
depends on nonlinear localization nature. They were neglected in several research papers. In these studies,
the accumulated errors increased with time due to the linearity localization problem. In the present study,
a cooperative localization method based on V2I communication and distance information in vehicular
networks is proposed for improving the estimates of vehicles’ initial positions. This method assumes that
the virtual RSUs based on mobility measurements help reduce installation costs and facilitate in handling
fault environments. The extended Kalman filter algorithm is a well-known estimator in nonlinear problem,
but it requires well initial vehicle position vector and adaptive noise in measurements. Using the proposed
method, vehicles’ initial positions can be estimated accurately. The experimental results confirm that the
proposed method has superior accuracy than existing methods, giving a root mean square error of
approximately 1 m. In addition, it is shown that virtual RSUs can assist in estimating initial positions in
fault environments.
IRJET - Security and Privacy by IDS SystemIRJET Journal
This document summarizes a research paper that proposes an intrusion detection system (IDS) to detect spoofing attacks in wireless sensor networks. The IDS monitors node activities and detects if a node is behaving abnormally or attacking the network. If an attack is detected, the IDS sends an alarm message to the affected node to isolate the attacker. The paper simulates this approach using OTCL language in Network Simulator 2 on Linux. The results show the IDS can efficiently detect spoofing attackers in the wireless network.

The internet of things (IoT) is a revolutionary innovation in many aspects of our society including interactions, financial activity, and global security such as the military and battlefield internet. Due to the limited energy and processing capacity of network devices, security, energy consumption, compatibility, and device heterogeneity are the long-term IoT problems. As a result, energy and security are critical for data transmission across edge and IoT networks. Existing IoT interoperability techniques need more computation time, have unreliable authentication mechanisms that break easily, lose data easily, and have low confidentiality. In this paper, a key agreement protocol-based authentication mechanism for IoT devices is offered as a solution to this issue. This system makes use of information exchange, which must be secured to prevent access by unauthorized users. Using a compact contiki/cooja simulator, the performance and design of the suggested framework are validated. The simulation findings are evaluated based on detection of malicious nodes after 60 minutes of simulation. The suggested trust method, which is based on privacy access control, reduced packet loss ratio to 0.32%, consumed 0.39% power, and had the greatest average residual energy of 0.99 mJoules at 10 nodes.

Wireless sensor networks (WSNs) became the backbone of the internet of things (IoT). IoT applications are vital and demand specific quality of service (QoS) requirements. In addition, security has become a primary concern to provide secure communication between wireless nodes, with additional challenges related to the node’s computational resources. Particular, the design of secure and resource efficient routing protocol is a critical issue in the current deployment of WSNs. Therefore, this paper proposes a novel secure-trust aware routing protocol (ST2A) that provides secure and reliable routing. The proposed protocol establishes communication routes based on calculated trust value in joint with a novel cluster head selection algorithm in the hierarchical routing process. The proposed trust-aware routing algorithm improves the routing security in WSN and optimizes many performance metrics related to WSNs unique characteristics. The results of simulation validate the feasibility of the proposed algorithm for enhancing the network lifetime up to 18% and data delivery by 17% as compared with some state-of-the-art routing algorithms.

Simulation results using MEMSIC sensor nodes showed the proposed approach reduces energy consumption and improves data delivery compared to existing methods.
SECURE ROUTING PROTOCOL TO MITIGATE ATTACKS BY USING BLOCKCHAIN TECHNOLOGY IN...IJCNCJournal
MANET is a collection of mobile nodes that communicate through wireless networks as they move from one
point to another. MANET is an infrastructure-less network with a changeable topology; as a result, it is
very susceptible to attacks. MANET attack prevention represents a serious difficulty. Malicious network
nodes are the source of network-based attacks. In a MANET, attacks can take various forms, and each one
alters the network's operation in its unique way. In general, attacks can be separated into two categories:
those that target the data traffic on a network and those that target the control traffic. This article explains
the many sorts of assaults, their impact on MANET, and the MANET-based defence measures that are
currently in place. The suggested SRA that employs blockchain technology (SRABC) protects MANET from
attacks and authenticates nodes. The secure routing algorithm (SRA) proposed by blockchain technology
safeguards control and data flow against threats. This is achieved by generating a Hash Function for every
transaction. We will begin by discussing the security of the MANET. This article's second section explores
the role of blockchain in MANET security. In the third section, the SRA is described in connection with
blockchain. In the fourth phase, PDR and Throughput are utilised to conduct an SRA review using
Blockchain employing PDR and Throughput. The results suggest that the proposed technique enhances

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Wide application of proportional-integral-differential (PID)-regulator in industry requires constant improvement of methods of its parameters adjustment. The paper deals with the issues of optimization of PID-regulator parameters with the use of neural network technology methods. A methodology for choosing the architecture (structure) of neural network optimizer is proposed, which consists in determining the number of layers, the number of neurons in each layer, as well as the form and type of activation function. Algorithms of neural network training based on the application of the method of minimizing the mismatch between the regulated value and the target value are developed. The method of back propagation of gradients is proposed to select the optimal training rate of neurons of the neural network. The neural network optimizer, which is a superstructure of the linear PID controller, allows increasing the regulation accuracy from 0.23 to 0.09, thus reducing the power consumption from 65% to 53%. The results of the conducted experiments allow us to conclude that the created neural superstructure may well become a prototype of an automatic voltage regulator (AVR)-type industrial controller for tuning the parameters of the PID controller.

A review on features and methods of potential fishing zoneIJECEIAES
This review focuses on the importance of identifying potential fishing zones in seawater for sustainable fishing practices. It explores features like sea surface temperature (SST) and sea surface height (SSH), along with classification methods such as classifiers. The features like SST, SSH, and different classifiers used to classify the data, have been figured out in this review study. This study underscores the importance of examining potential fishing zones using advanced analytical techniques. It thoroughly explores the methodologies employed by researchers, covering both past and current approaches. The examination centers on data characteristics and the application of classification algorithms for classification of potential fishing zones. Furthermore, the prediction of potential fishing zones relies significantly on the effectiveness of classification algorithms. Previous research has assessed the performance of models like support vector machines, naïve Bayes, and artificial neural networks (ANN). In the previous result, the results of support vector machine (SVM) were 97.6% more accurate than naive Bayes's 94.2% to classify test data for fisheries classification. By considering the recent works in this area, several recommendations for future works are presented to further improve the performance of the potential fishing zone models, which is important to the fisheries community.

As demand for smaller, quicker, and more powerful devices rises, Moore's law is strictly followed. The industry has worked hard to make little devices that boost productivity. The goal is to optimize device density. Scientists are reducing connection delays to improve circuit performance. This helped them understand three-dimensional integrated circuit (3D IC) concepts, which stack active devices and create vertical connections to diminish latency and lower interconnects. Electrical involvement is a big worry with 3D integrates circuits. Researchers have developed and tested through silicon via (TSV) and substrates to decrease electrical wave involvement. This study illustrates a novel noise coupling reduction method using several electrical involvement models. A 22% drop in electrical involvement from wave-carrying to victim TSVs introduces this new paradigm and improves system performance even at higher THz frequencies.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants.

Fossil fuel consumption increased quickly, contributing to climate change
that is evident in unusual flooding and draughts, and global warming. Over
the past ten years, women's involvement in society has grown dramatically,
and they succeeded in playing a noticeable role in reducing climate change.
A bibliometric analysis of data from the last ten years has been carried out to
examine the role of women in addressing the climate change. The analysis's
findings discussed the relevant to the sustainable development goals (SDGs),
particularly SDG 7 and SDG 13. The results considered contributions made
by women in the various sectors while taking geographic dispersion into
account. The bibliometric analysis delves into topics including women's
leadership in environmental groups, their involvement in policymaking, their
contributions to sustainable development projects, and the influence of
gender diversity on attempts to mitigate climate change. This study's results
highlight how women have influenced policies and actions related to climate
change, point out areas of research deficiency and recommendations on how
to increase role of the women in addressing the climate change and
achieving sustainability. To achieve more successful results, this initiative
aims to highlight the significance of gender equality and encourage
inclusivity in climate change decision-making processes.
Voltage and frequency control of microgrid in presence of micro-turbine inter...IJECEIAES
The active and reactive load changes have a significant impact on voltage
and frequency. In this paper, in order to stabilize the microgrid (MG) against
load variations in islanding mode, the active and reactive power of all
distributed generators (DGs), including energy storage (battery), diesel
generator, and micro-turbine, are controlled. The micro-turbine generator is
connected to MG through a three-phase to three-phase matrix converter, and
the droop control method is applied for controlling the voltage and
frequency of MG. In addition, a method is introduced for voltage and
frequency control of micro-turbines in the transition state from gridconnected mode to islanding mode. A novel switching strategy of the matrix
converter is used for converting the high-frequency output voltage of the
micro-turbine to the grid-side frequency of the utility system. Moreover,
using the switching strategy, the low-order harmonics in the output current
and voltage are not produced, and consequently, the size of the output filter
would be reduced. In fact, the suggested control strategy is load-independent
and has no frequency conversion restrictions. The proposed approach for
voltage and frequency regulation demonstrates exceptional performance and
favorable response across various load alteration scenarios. The suggested
strategy is examined in several scenarios in the MG test systems, and the
simulation results are addressed.

Precisely characterizing Li-ion batteries is essential for optimizing their
performance, enhancing safety, and prolonging their lifespan across various
applications, such as electric vehicles and renewable energy systems. This
article introduces an innovative nonlinear methodology for system
identification of a Li-ion battery, employing a nonlinear autoregressive with
exogenous inputs (NARX) model. The proposed approach integrates the
benefits of nonlinear modeling with the adaptability of the NARX structure,
facilitating a more comprehensive representation of the intricate
electrochemical processes within the battery. Experimental data collected
from a Li-ion battery operating under diverse scenarios are employed to
validate the effectiveness of the proposed methodology. The identified
NARX model exhibits superior accuracy in predicting the battery's behavior
compared to traditional linear models. This study underscores the
importance of accounting for nonlinearities in battery modeling, providing
insights into the intricate relationships between state-of-charge, voltage, and
current under dynamic conditions.
Smart grid deployment: from a bibliometric analysis to a surveyIJECEIAES
Smart grids are one of the last decades' innovations in electrical energy.
They bring relevant advantages compared to the traditional grid and
significant interest from the research community. Assessing the field's
evolution is essential to propose guidelines for facing new and future smart
grid challenges. In addition, knowing the main technologies involved in the
deployment of smart grids (SGs) is important to highlight possible
shortcomings that can be mitigated by developing new tools. This paper
contributes to the research trends mentioned above by focusing on two
objectives. First, a bibliometric analysis is presented to give an overview of
the current research level about smart grid deployment. Second, a survey of
the main technological approaches used for smart grid implementation and
their contributions are highlighted. To that effect, we searched the Web of
Science (WoS), and the Scopus databases. We obtained 5,663 documents
from WoS and 7,215 from Scopus on smart grid implementation or
deployment. With the extraction limitation in the Scopus database, 5,872 of
the 7,215 documents were extracted using a multi-step process. These two
datasets have been analyzed using a bibliometric tool called bibliometrix.
The main outputs are presented with some recommendations for future
research.
Use of analytical hierarchy process for selecting and prioritizing islanding ...IJECEIAES
One of the problems that are associated to power systems is islanding
condition, which must be rapidly and properly detected to prevent any
negative consequences on the system's protection, stability, and security.
This paper offers a thorough overview of several islanding detection
strategies, which are divided into two categories: classic approaches,
including local and remote approaches, and modern techniques, including
techniques based on signal processing and computational intelligence.
Additionally, each approach is compared and assessed based on several
factors, including implementation costs, non-detected zones, declining
power quality, and response times using the analytical hierarchy process
(AHP). The multi-criteria decision-making analysis shows that the overall
weight of passive methods (24.7%), active methods (7.8%), hybrid methods
(5.6%), remote methods (14.5%), signal processing-based methods (26.6%),
and computational intelligent-based methods (20.8%) based on the
comparison of all criteria together. Thus, it can be seen from the total weight
that hybrid approaches are the least suitable to be chosen, while signal
processing-based methods are the most appropriate islanding detection
method to be selected and implemented in power system with respect to the
aforementioned factors. Using Expert Choice software, the proposed
hierarchy model is studied and examined.
Enhancing of single-stage grid-connected photovoltaic system using fuzzy logi...IJECEIAES
The power generated by photovoltaic (PV) systems is influenced by
environmental factors. This variability hampers the control and utilization of
solar cells' peak output. In this study, a single-stage grid-connected PV
system is designed to enhance power quality. Our approach employs fuzzy
logic in the direct power control (DPC) of a three-phase voltage source
inverter (VSI), enabling seamless integration of the PV connected to the
grid. Additionally, a fuzzy logic-based maximum power point tracking
(MPPT) controller is adopted, which outperforms traditional methods like
incremental conductance (INC) in enhancing solar cell efficiency and
minimizing the response time. Moreover, the inverter's real-time active and
reactive power is directly managed to achieve a unity power factor (UPF).
The system's performance is assessed through MATLAB/Simulink
implementation, showing marked improvement over conventional methods,
particularly in steady-state and varying weather conditions. For solar
irradiances of 500 and 1,000 W/m2
, the results show that the proposed
method reduces the total harmonic distortion (THD) of the injected current
to the grid by approximately 46% and 38% compared to conventional
methods, respectively. Furthermore, we compare the simulation results with
IEEE standards to evaluate the system's grid compatibility.
Enhancing photovoltaic system maximum power point tracking with fuzzy logic-b...IJECEIAES
Photovoltaic systems have emerged as a promising energy resource that
caters to the future needs of society, owing to their renewable, inexhaustible,
and cost-free nature. The power output of these systems relies on solar cell
radiation and temperature. In order to mitigate the dependence on
atmospheric conditions and enhance power tracking, a conventional
approach has been improved by integrating various methods. To optimize
the generation of electricity from solar systems, the maximum power point
tracking (MPPT) technique is employed. To overcome limitations such as
steady-state voltage oscillations and improve transient response, two
traditional MPPT methods, namely fuzzy logic controller (FLC) and perturb
and observe (P&O), have been modified. This research paper aims to
simulate and validate the step size of the proposed modified P&O and FLC
techniques within the MPPT algorithm using MATLAB/Simulink for
efficient power tracking in photovoltaic systems.
Adaptive synchronous sliding control for a robot manipulator based on neural ...IJECEIAES
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

A remote laboratory utilizing field-programmable gate array (FPGA) technologies enhances students’ learning experience anywhere and anytime in embedded system design. Existing remote laboratories prioritize hardware access and visual feedback for observing board behavior after programming, neglecting comprehensive debugging tools to resolve errors that require internal signal acquisition. This paper proposes a novel remote embeddedsystem design approach targeting FPGA technologies that are fully interactive via a web-based platform. Our solution provides FPGA board access and debugging capabilities beyond the visual feedback provided by existing remote laboratories. We implemented a lab module that allows users to seamlessly incorporate into their FPGA design. The module minimizes hardware resource utilization while enabling the acquisition of a large number of data samples from the signal during the experiments by adaptively compressing the signal prior to data transmission. The results demonstrate an average compression ratio of 2.90 across three benchmark signals, indicating efficient signal acquisition and effective debugging and analysis. This method allows users to acquire more data samples than conventional methods. The proposed lab allows students to remotely test and debug their designs, bridging the gap between theory and practice in embedded system design.

Efficiently identifying and resolving code smells enhances software project quality. This paper presents a novel solution, utilizing automated machine learning (AutoML) techniques, to detect code smells and apply move method refactoring. By evaluating code metrics before and after refactoring, we assessed its impact on coupling, complexity, and cohesion. Key contributions of this research include a unique dataset for code smell classification and the development of models using AutoGluon for optimal performance. Furthermore, the study identifies the top 20 influential features in classifying feature envy, a well-known code smell, stemming from excessive reliance on external classes. We also explored how move method refactoring addresses feature envy, revealing reduced coupling and complexity, and improved cohesion, ultimately enhancing code quality. In summary, this research offers an empirical, data-driven approach, integrating AutoML and move method refactoring to optimize software project quality. Insights gained shed light on the benefits of refactoring on code quality and the significance of specific features in detecting feature envy. Future research can expand to explore additional refactoring techniques and a broader range of code metrics, advancing software engineering practices and standards.

Rapidly and remotely monitoring and receiving the solar cell systems status parameters, solar irradiance, temperature, and humidity, are critical issues in enhancement their efficiency. Hence, in the present article an improved smart prototype of internet of things (IoT) technique based on embedded system through NodeMCU ESP8266 (ESP-12E) was carried out experimentally. Three different regions at Egypt; Luxor, Cairo, and El-Beheira cities were chosen to study their solar irradiance profile, temperature, and humidity by the proposed IoT system. The monitoring data of solar irradiance, temperature, and humidity were live visualized directly by Ubidots through hypertext transfer protocol (HTTP) protocol. The measured solar power radiation in Luxor, Cairo, and El-Beheira ranged between 216-1000, 245-958, and 187-692 W/m 2 respectively during the solar day. The accuracy and rapidity of obtaining monitoring results using the proposed IoT system made it a strong candidate for application in monitoring solar cell systems. On the other hand, the obtained solar power radiation results of the three considered regions strongly candidate Luxor and Cairo as suitable places to build up a solar cells system station rather than El-Beheira.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

It is an open research issues to find the reliability in terms of trust by the regular MANET nodes
with the mobile-agent nodes, which ensures the degree of security to establish route in the MANET with
mobile-agent nodes. The initial approaches for finding the node trust level were adopted at the local layer of
the nodes that limits the auditing accuracy and capacity to identify the types of attacks [13].
The further evolution in the direction of the node trust determination, the methods uses the local level
capacity along with cooperative mechanisms to detect the various kinds of the attacks, but these approaches
poses additional overhead as many control messages are required to be imposed to exchanges the updated
information at both local level as well as in collaborative communication that leads it to work in
a cluster [14-15]. The methodologies for the security aspects in terms of identifying the malicious nodes
implanted or participated into the MANET is given to a particular node in a cluster that minimizes overheads
to an extend but due to distributed and highly dynamic nature of the network it poses again polynomial
complexities when it is a large-scale network.
The approach of additional methods like signature, anomaly engine etc were developed to mark
a suspicious node as malicious and avoid it from the routing but it makes the iterative network partition
which is not a perfect solution to balance the requirement of the balance between the security and
the network performance [16]. Thus, inspite of a control mechanism for the attacks and threats due to
malicious node a method of mitigating the effect is adopted based on the strategic decision made by
the nodes and the mobile agents that ensure a balance between the minimization of loss due to security
threats and maximization of the network performance QoS parameters balancing both resources even in
the large network which a demand of the future applications. This paper presents a mathematical model of
a decision-making strategy among the regular-manet nodes and the mobile-agent nodes to establish a trust for
the reliable communications. The organization of the proposed manuscript is as follows: Section 1 discusses
about the background of the existing studies associated with agent based solution toward security, security
briefs of research problems identified and highlights about the research methodology adopted for solving
the problems of existing security issues in MANET. Section 2 presents an illustrative discussion of system
design followed by discussion of the result analysis in Section 3. Finally, the conlusion of the proposed
system is briefed in Section 4.
There is absolutely no doubt of presence of archives of massive literature highlighting about
the techniques required for securing the MANET system. The most recent study carried out by Wang and
Li [17] have presented a secure communication mechanism that selects the agent nodes which contructing
routes. These techniques ensure reliable delivery of packet between the agent nodes. Another recent work of
Shehada et al. [18] has adopted trust based scheme along with reputation in order to model a mobile agent
focusing on social network. The technique uses an adaptive process in order to evolve up with a decision
makig system. Agent-based approaches are also used by Harrabi et al. [19] where the authors have used it
over vehicular network. The work carried out by Rohankar [20] throws an interesting usage of agent-based
approach over wireless adhoc network using predictive approachover conventional MANET routing scheme.
However, the approach was more focus on communication establishment and less focus on security.
Study considering securing adhoc network using mobile agents was seen in the work of Abosamra et al. [21]
where authors have used encryption protocol for securing the communication. Combination of agent usage
and trust is another frequently adopted approach for securing communication in MANET.
The work of Halim et al. [22] has introduced a selective data forwarding scheme using mathematical
model using the role of agent for both routing and monitoring system considering on-demand routing
scheme. The study outcome shows better performance in latency and detection. The agent-based mechanism
was also used in IoT and cloud ecosystem as MANET finds its ultimate deployment over this.
The recent works carried out by Magarino et al. [23] have used agent-based approach for facilitating mining
massive data. Another recent work of Fortino et al. [24] has discussed how agent-based mechanism can be
embedded with smart objects in IoT environment. The work of Gargees and Scott [25] has presented
a technique for facilitating data structurization over IoT media in order to extract pattern of communication.
However, such studies are more data oriented and less on security.
Adoption of multi-agents was reported to be used in the study carried out by Quan et al. [26, 27]
which emphasizes on both fault tolerance and security breach prevention. Another work carried out
by Fortino et al. [28] have discussed that hybridizing the charecteristics of agents has multiple benefits of
communication system assessment in an IoT. The study carried out by Santos et al. [29] have discussed about
the usage of softwarer agents along with incorporation of intelligence. The work carried out
by Hsieh et al. [30] have constructed a design of an agent that using event-driven approach for constructing
the communication mechanism in IoT. Therefore, there are various mechanisms evident in existing approach
where agent-based approach has been utilized. However, there is less inclination of the existing schemes to
address security problems associated with MANET and are more focus on re-defining communication system
on wireless network. The next section briefs of research problems.

The significant research problems are as follows:
- None of the existing agent-based scheme has addressed the complex security problems in MANET or
likewise scenario.
- The adversaries are well defined in existing security schemes that uses mobile agents and hence they are
not applicable if the adversary tactics changes.
- Developing intrusion detection system using mobile agent in presence of dynamic adversary is not much
emphasized in existing system.
- There are no benchmarked studies focusing on solving the critical security problems in case the mobile
agents are compromised.
Therefore, the problem statement of the proposed study can be stated as “It is quite a challenging task to
construct a framework capable of identifying the discrete behaviour of mobile agents such that agent-based
communication system can be further boosted for MANET communication”
The proposed system is implemented using analytical research methodology where the prime focus
is offered towards constructing a secured scheme to offer selection of trusted mobile agents in MANET.
Basically, mobile agents assist in multiple ways to bridge the communication demands in MANET but are
highly vulnerable to security threats. Therefore, proposed system considers a presence of adversarial model
where there is no apriori information about the criticality of attack in MANET by malicious mobile agents.
The scheme adopted as a solution is showcased in Figure 1

The above Figure.1 exhibits that the proposed system considers modeling mobile agents with
inclusion of two types of task to be executed by them. Owing to presence of common task, it is highly
challenging to distinguish regular node from malicious mobile agent. Although, there are distinct
charecteristics too, but they are rarely expected to be exhibited by malicious mobile agent in order to resist
the chances to get entrapped by the security system.Therefore, the proposed model constructs a simplified
mathematical modeling on the basis of probability theory in order to evolve up in a potential and reliable
decision making system. The core components of the proposed mathematical modeling are trust evaluation,
decision making, and fairness communication. A novel concept of trio communication policy has been
constructed which governs all the possibilities of communication behaviour of both the type of nodes.
The next section illustrates about the system design and implementation.
2. SYSTEM IMPLEMENTATION
The complete target of the system design is to construct a mechanism that offers enhanced
capability to identify the malicious intention of mobile agent. The outcome of the implementation is mainly
focused on quarantining such adversary node to participate in communication process. The backbone concept
of system implementation is to construct a reliable intrusion detection system mainlyover MANET.
These section briefs of complete information associated with the system implementation.

2.1. Modelling assumptions
The primary assumption of the proposed system is that there is no apriori information associated
with the identity of the adversary node. This assumption will offer evidence of resistivity capability of
regular node against malicious node. The secondary assumption of the proposed system is that adversary will
always target mobile agents as their initial source of launching attack. The rationae behind this assumption is
that network resource used for compromising a regular node is more than that of mobile agent. If one mobile
agent is compromised than the attack will spread exponentially because one mobile agent assists in
communication for multiple neighboring nodes. The tertiary assumption is that there are possibilities of
slight variation in observation for adversarial mobile agent; however, study considers such probability to be
very low. This justification behind this assumption is that the proposed system performs intrusion detection
system on the basis of monitoring of neighboring mobile agents. Owing to inclusion of dynamic topology in
MANET, there are some possibilities that a good malicious node could be declared as adversary or vice-
versa. This challenge is addressed by using a threshold-based evaluation system which reduces such chances.
2.2. Mathematical model
Probability-based modeling has been used for construction the mathematical framework of proposed
system for assessing the trust factor from the mobile agents. The proposed study considers that there are two
kinds of mobile agents i.e. regular mobile agent and malicious mobile agent. An adversarial modeling is
carried out by considering correlated trust parameter and uncorrelated trust parameters represented as,
λct={Fp, Rj} & λuct={Cn, Dnt} (1)
The correlated trust parameter λct will mean a set of certain task executed by mobile agents, which
are found correlated in both regular and adversary mobile agents. The study considers Fp (forward packet)
and Rj (reject packet) which can be carried out by both regular and adversary mobile agent, which makes it
hard to distinguish them in intrusion detection system. The uncorrelated trust parameter λuct will mean certain
distinct task explicit to node type viz. i) the proposed study consider Cn (compromize / launch malicious
code) to be executed by adversary only while Dnt (declare node trust) is explicitely a task carried out by
regular mobile agent. These operations can only distinguise if the mobile agent is malicious or non-harmful.
The essential components of the proposed mathematical modeling are as follows:
- Trust Evaluation: The proposed system performs three types of trust evaluation in order to ascertain
the trust worthiness of the communicating mobile agent using two parameters viz. i) Q1(computing
frequencies of Fp) and ii) Q2 (computing frequencies of Rj). The first trust evaluation factor TR is termed
as regular trust and is computed as Q1/(Q1+Q2) while the second trust evaluation factor TM is termed as
malicious trust and is computed as Q2/(Q1+Q2). The third trust evaluation Tam is termed as ambiguous
trust and is computed as following:
Tam=c. τ1/τ2 (2)
In the above mathematical expression, the variable c is network constant while the variable τ1 is scalar
product of TR and TM. The variable τ2 is computed as scalar squared product and summation of Q1 and Q2
respectively.
- Decision Making: In order to make a decision, it is essential for the proposed system to observe the trend
of communication for all the mobile agents. For this purpose, the proposed system considers little more
parametric computation associated with profit and number of resources being used by mobile agents.
This behavioural trend will offer more inclusive disclosure of their malicious intention. The initial
decision making towards capturing malicious intention of mobile agent will be seen from the trend of
ambiguous trust Tam values (2). Normally, a declining trend of numerical value of ambiguous trust
Tam will show concrete case of adversary while a regular node will never be shown to be has declining
trend owing to the usage of cut-off Thr which can be given as per the demand of security. Apart from this,
a second layer of cut-off is used in order to prevnt any possibility of outliers in declaration of regular
mobile agent to malicious one.
- Fairness Communication: As the proposed system is designed on the basis of neighboring mobile agent
behavioural monitoring system, there are chances that certain numerical evaluation could lead to wrong
misinterpretation of mobile agents to be malicious. This situation is avoided in following manner.
The proposed system develops a concept of fairness to both malicious and regular mobile agent in order
to ensure that the system can still identify the malicious behaviour in case of ambiguous decision making.
According to this fairness concept, the regular mobile agent is considered to more inclination towards
identifying and updating the threat (i.e. Dnt) whereas the malicious node will be more inclined towards

Trust correlation of mobile agent nodes with a regular node in a Adhoc network … (Chethan B. K.)
1565
launching malicious codes to the neighboring mobile nodes in MANET. This situation makes
the communication more challenging as both the agent types will try to gain more fairness. This situation
is solved by following when the regular mobile agent evaluates the trust of neighboring mobile agents;
it reconfirms the malicious intention by checking the trust value of the target mobile agent from its
neighboring nodes. That trust is then compared with the second layer of trust cut-off to finally declare
the target node to be malicious.
2.3. Execution flow
The proposed system initiates with the configuraton of deployment region D, number of mobile
agents n, and proportion of the intruder node inode. Apart from this variable, the proposed system also
performs initialization of few more parameters e.g. P(Fp) profit allocated to agent for performing Fp, γ(FP)
number of resourced involved in performing FP, P(Cn) profit allocated to agent for performing Cn.
The next part of the implementation is carried out for estimating Q1, Q2, pa, and Tam for all the mobile agents
present in deployment region D. The proposed system implements three different communication policies as
a part of contribution for assisting in better decision making as well as mapping with real-world greedy
scenario of the mobile agents. The three communication policies are as follows:
- Communication Policy-1 (CP1): According to this policy, the current mobile agents will have complete
information about the next task to be executed by the mobile agent and vice-versa.
- Communication Policy-2 (CP2): In this policy, a probability is assigned to each undertaking of CP1
thereby allowing the mobile agents to arbitrarily opt for CP1. As there are infinite number between
the probability limits so there is massive number of combination of CP1 for each mobile agent.
- Communication Policy-3 (CP3): In this policy, the current mobile agents don’t have complete or has
fuzzy information about the communication policy of target mobile agents. One interesting fact of this
communication policy is that tactic adopted by the mobile agent gives indication about the trust factor on
the basis of historical information.
All the above communication policies are constructed on the basis of various tasks i.e. FP, Cn, RJ, and Dnt.
The proposed system is then assessed on the basis of combination of all three communication policies
adopted by regular and malicious mobile agents. The assessment is carried out by selecting a source mobile
agent and destination node. This principle is used for identification of the malicious mobile agents whose
algorithmic steps is shown as below:
Algorithm for Identification of Malicious Agent
Input: n, ψ, Thr, pa
Output: F
Start
1. For i=1:n
2. While ψ<Thr
3. If pa<cond1 then
4. opt Fp(prob1)
5. Else
6. opt Fp(prob2)
7. End
8. End
9. Fflag vulnerable mobile agent
10. End
End
The above algorithm takes the input of n (total number of mobile agents), ψ (selected trust),
Thr (cut-off trust), and pa (probability of adversary node) that after processing yields and outcome of
F (Declaring Adversary Node). According to the above mentioned algorithm, the computation towards
the identification of the malicious agents is carriedout considering all the agents n (Line-1). The complete
algorithm considers CP3 as the tactic adopted for mobile agent of unknown trust nature (which is under
observation). Under this scheme, the source mobile agent performs evaluation of the target mobile agents in
order to conclude if they the regular or malicious mobile agents. This evaluation is carried out by a variable ψ
representing probability of vulnerable mobile agents and is computed by scalar product of probability of
adversary node pa and (1-Tam), where the later variable represents residual trust ambiguity (Line-2). It will
therefore mean that if the variable ψ is found more than cut-off Thr than it will just mean that the target node
doesn’t have malicious intention. However, it still doesn’t give a confirmation that the target node is 100%
regular mobile agent. For this purpose, it performs further assessment.

The system compares probability of adversary node pa with conditional parameter cond1.
The computation of the conditional parameter is carried out by using probability where the variable cond1
represents favorable chances of data forwarding by target mobile agent divided by total chances of both data
forwarding and launching attack. The estimation of first parameter is carried out by P(FP)-γ(FP) while
the later parameter is estimated as P(FP)+P(Cn). A closer look into the formation of the variable cond1 will
show that it represents the best chances of data forwarding by the mobile agent in present of all
the probabilities connected with both data forwarding and launching attack. Therefore, the conditional
statement in Line-2 represents that probability that the target mobile agent is an adversary and that is found
less than conditional parameter cond1. In such positive case, it will mean that the target mobile node could be
malicious but it doesn’t have any harmful action to be launched at that time.
Hence, there are good chances that target mobile node will perform data packet forwarding with
higher probability prob1 (Line-4). However, if the condition found to be Pa greater than it will mean that
there are some good chances to confirm that the target node has malicious intention which can be calculated
by different probability i.e. prob2(Line-6). The value of prob1 is 1 as it is higher probability score while
the second probability prob2 is estimated as favorable chances of attack (γ(Cn)- γ(FP)) divided by total attack
chances (P(Cn)). Finally, the system retains the latest value of Q1, Q2, and pa and transmits to all neighboring
mobile agents about the conclusion it draws from evaluation of target mobile agent in terms of flag message
F (Line-9). Therefore, the proposed algorithm allows the source mobile agents / nodes in MANET to make
use of probability on the basis of few operational parameters (Q1, Q2, and pa) to estimate the malicious
intention of the target mobile agent. The strength of this algorithm is that it offers multi-tier checks for
the trust factor associated with the target mobile agents where trust score is extracted directly as well as from
the neighboring nodes of the target mobile agents. Another interesting part of this algorithm is that even if
the target mobile agent is not 100% confirmed tobe malicious, but if itscurrent intention is just to forward
data packet than it is permitted to do so.
The logic behind this operation is that – a malicious node will try to bypass all security system in
MANET as the network is highly dynamic order and chances of using distributed security protocols are
usually high. Therefore, in order to resist disclosure of the malicious intention of an adversary they will act as
a friendly node by participating as relay or intermediate mobile agents. An adversary will continue to do this
until and unless they get an appropriate opportunity to launch malicious codes. Another interesting point of
this algorithm is its incorporation of the fairness concept for both regular and malicious mobile agents.
Usually, a malicious mobile agent will continue forwarding the packet as that is not their main intention;
however, they will need to do so for not getting themselves catured by the security system. As it will require
consumption of resources which is actually destined for launching an attack, so a threshold value can be
selected for this. For an example, a malicious node cannot use 50% of their resources just to do FP operation
as they also require retaining resources for Cn operation. This concept is used in proposed system which can
identify malicious mobile agent to a large extent. However, if their action is found to be within a tolerable
cut-off of threshold, it will eventually mean that probability of launching attack is less by the malicious node
and there is no harm allowing them in data packet forwarding.
Adopting this mechanism, all the target node is under consistent observation. Apart from this,
there is also possibility about the wrong judgement about the legitimacy of the target mobile agent in
communication region. For this purpose, the proposed system should first check if the anticipated value of
the Dnt is found to be more than maximum score of probability of FP and Cn. In such condition, it will mean
that there are partial changes of outliers too. This problem is solved by assesing the variability of
the probability score. A penalty factor is allocated in case of violation of the fairness factor by the regular
malicious agent. Hence, irrespective of slight chances that some target nodes by misjudged, but in majority of
cases the judgement is correct as the trust computation is carried out considering local and global trust factor.
One of the interesting effectiveness of this security protocol is that it drains out the resources of the malicious
nodes as neither it allows to participate in routing process (as long as their probability of launching attack is
not found defined under existing communication policy) nor it allows to launch an attack.
Hence, the proposed system offers a significant cost control by avoiding usage of any comlex encryption
algorithm in order to resist any possibilities of intrusion.
3. RESULT ANALYSIS
The scripting of the proposed security scheme has been carried out over MATLAB. The analysis
considers that is maximum loss could occur to a regular node if they generate falsified report. Therefore
the cut-off value of the trust could be considered to be somewhat ideally between 0.4-0.5 and simulation area
considered is 1000x1200m2
. The assessment of proposed study was carried out by comparing its performance

with existing security scheme e.g. SAODV [31] and SLSP [32] with respect to multiple performance
parameters e.g. latency, overhead, throughput, and processing time.
Figure 2 highlights the graphical outcome of comparative analysis that shows proposed system
offers better performance in every aspect in comparison to existing system. The prime reason behind this are
existing security schemes offers protection by assuming that the adversary is well known and all its actions
are very much well defined. This is highly unpractical scenario and MANET when integrated with IoT can
invoke adversary with exponentially high dynamicity. On the other hand, proposed system is capable to
identify the malicious intention without even knowing exact specification of the adversary. The complete
simulation is carried out considering that specific number of mobile agents where a both good and rogue
agent exists in number but not in terms of identity. Hence, the proposed scheme supports faster updating
process resulting in lower latency as shown in Figure 2 (a) and faster processing time Figure 2 (d).
Apart from this, owing to the adoption of the fairness concept, it was seen that proposed system
even exploits malicious nodes if they make themselves available for data forwarding. Therefore, a higher
controllable environment is developed which ensures that malicious mobile agent doesn’t invoke attack and
permits them to forward a data packet, This is also a good prevention approach as malicious node will soon
drain out of energy which was primarlity destined for launching attack. This causes non-significant effect on
the throughput resulting in a good balance between the security enhancement and data communication
performance as shown in Figure 2(c). Apart from this the updating of the trust factor of the regular or
malicious node is carried out only for the communicating nodes and neighboring nodes. This causes highly
reduced overhead effect on the communication in MANET system. Therefore, the proposed system can be
claimed of offering simplified solution towards upgrading security features for evaluating trust for mobile
agents in MANET.

4. CONCLUSION
Presence of a mobile agent in a dynamic network like MANET could offer an immese boost up in
the communication process as they acts as a communication bridge between two communicating nodes. It will
eventually mean that compromising mobile agents can break loose exponentially higher degree of
vulnerability in the entire network. Therefore this challenging scenario cannot be dealt using existing
mechanism which is highly application specific as well as attack-specific solution. Therefore, the proposed
system offers discussion of a framework that uses probabilistic model for defining probable behaviour of
communication of both regular node and malicious mobile agents in order to discretely identify them.
The significant contribution of the proposed model are i) zero dependency on iterative based cryptographic
protocols in MANET, ii) cost effective solution towards security without aprioi information about the attacks,
and iii) it does balance the communication demands of MANET.
