DESIGN AND IMPLEMENTATION OF A TRUST-AWARE ROUTING PROTOCOL FOR LARGE WSNSIJNSA Journal
The domain of Wireless Sensor Networks (WSNs) applications is increasing widely over the last few years. As this new type of networking is characterized by severely constrained node resources, limited network resources and the requirement to operate in an ad hoc manner, implementing security functionality to protect against adversary nodes becomes a challenging task. In this paper, we present a trust-aware, location-based routing protocol which protects the WSN against routing attacks, and also supports large-scale WSNs deployments. The proposed solution has been shown to efficiently detect and avoid malicious nodes and has been implemented in state-of-the-art sensor nodes for a real-life test-bed. This work focuses on the assessment of the implementation cost and on the lessons learned through the design, implementation and validation process.

Trust Providence in Delay Tolerant Networkstheijes
The network consists of several nodes, some nodes represents malicious and selfish behavior. This gives the heavy threat for the routing in Delay Tolerant networks(DTNs). The DTNs have unique characteristic so designing a misbehavior detection scheme is very difficult. The probabilistic misbehavior detection scheme that is iTrust, is established for secure routing in DTN. The iTrust introduces a Trusted Authority (TA) for detecting the node’s behavior. By collecting the routing evidences from the nodes the TA checks the node about its behavior then performs the appropriate actions for the behavior of nodes. TA gives the security of DTN routing at lower cost. The detection probability is correlated with a node’s reputation, this gives the dynamic detection probability based on the trust of users. The simulation results show that the proposed scheme is efficient for establishing trust with the DTNs.
PERFORMANCE ANALYSIS OF THE NEIGHBOR WEIGHT TRUST DETERMINATION ALGORITHM IN ...IJNSA Journal
Mobile ad-hoc networks (MANETs) are susceptible to attacks by malicious nodes that could easily bring down the whole network. Therefore, it is important to have
a reliable mechanism for detecting and isolating malicious nodes before they can do any harm to the network. One of the possible mechanisms is by using trust-based routing protocols. One of the main requirements of such protocols is to have a cost-effective trust determination algorithm. This paper presents the performance analysis of a recently developed trust determination algorithm, namely, the neighbor-weight trust determination (NWTD) algorithm. The performance of the algorithm is evaluated through simulation using the MANET simulator (MANSim). The simulation results demonstrated the reliability and effectiveness of the algorithm in identifying and isolating any maliciously behaving node(s) in a timely manner.

Dynamic Trust Management of Unattended Wireless Sensor Networks for Cost Awar...paperpublications3
Abstract: Unattended Wireless Sensor Networks (UWSNs) are characterized by long periods of disconnected operation and fixed or irregular intervals between sink visits. The absence of an online trusted third party implies that existing WSN trust management schemes are not applicable to UWSNs. In this paper, a trust management scheme for UWSNs to provide dynamic trust management is proposed. For trust data storage, geographic hash table is employed, it also helps to identify storage nodes and to significantly decrease storage cost. In order to mitigate trust fluctuations caused by environmental factors a subjective logic based consensus techniques is used. In this paper a set of trust similarity functions are exploited to detect trust outliers.
TRUST ORIENTED SECURITY FRAMEWORK FOR AD HOC NETWORKcscpconf
An ad hoc network is a group of wireless mobile hosts that are connected momentarily through
wireless connections in the dearth of any centralized control or some supporting services. The
mobile ad hoc network is at risk by its environment because of the vulnerabilities at channel and
node level. The conventional security mechanisms deals with only protecting resources from unauthorized access, but are not capable to safeguard the network from who offer resources. Adding trust to the on hand security infrastructures would improvise the security of these environments. A trust oriented security framework for adhoc network using ontological engineering approach is proposed by modeling ad hoc network, the OLSR (Optimized Link State Routing) protocol and trust model as OWL (Ontology Web language) ontologies, which are integrated using Jena. In this model, a trustor can calculate its trust about trustee and use the calculated trust values to make decisions depending on the context of the application or interaction about granting or rejecting it. A number of experiments with a potential implementation of suggested framework are performed to validate the characteristics of a trust oriented model suggested by the literature by this framework

A SECURE CLUSTER BASED COMMUNICATION IN WIRELESS NETWORK USING CRYPTOGRAPHIC ...IJNSA Journal
Mobile Adhoc Networks are becoming very popular in current Wireless Technology, which is been
associated to business, socially and in some critical applications like Military etc, The network which is
formed by self configuring wireless links which are connected to each other. These applications are
categorized by hostile environment that they serve while communicating between nodes. However in such
Wireless Network will be more exposed to different types of security attacks. The challenge is to meet
secure network communication. In this paper we focus on cluster based secure communication to improve
the reliability between clusters. In this scheme the Cluster Members (CM) submits a report to the Cluster
Head (CH) and temporarily stores Evidences as a security tokens. The reports contain digital signatures.
The CH will verify the consistency of the CM report and updates to Accounting Centre (AC). AC will verify
the uniformity of reports and clears the cryptographic operations. For attacker nodes, the security tokens
are requested to classify and expel the attacker nodes which submit wrong reports.
Scalable and Robust Hierarchical Group of Data in Wireless Sensor NetworksIJERA Editor
In many sensor applications, the data collected from individual nodes is aggregated at a base station or host computer. To reduce energy consumption, many systems also perform in-network aggregation of sensor data at intermediate nodes enrooted to the base station. Most existing aggregation algorithms and systems do not include any provisions for security, and consequently these systems are vulnerable to a wide variety of attacks. In particular, compromised nodes can be used to inject false data that leads to incorrect aggregates being computed at the base station. We discuss the security vulnerabilities of data aggregation systems, and present a survey of robust and secure aggregation protocols that are resilient to false data injection attacks. The Proposed SHIA Algorithm builds on the Secure Hierarchical In-Network Aggregation, in order to achieve not only secure but also efficient WSN data collection over a series of aggregations.
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.
Cluster Based Misbehaviour Detection and Authentication Using Threshold Crypt...CSCJournals
In mobile ad hoc networks, the misbehaving nodes can cause dysfunction in the network resulting in damage of other nodes. In order to establish secure communication with the group members of a network, use of a shared group key for confidentiality and authentication is required. Distributing the shares of secret group key to the group members securely is another challenging task in MANET. In this paper, we propose a Cluster Based Misbehavior Detection and Authentication scheme using threshold cryptography in MANET. For secure data transmission, when any node requests a certificate from a cluster head (CH), it utilizes a threshold cryptographic technique to issue the certificate to the requested node for authentication. The certificate of a node is renewed or rejected by CH, based on its trust counter value. An acknowledgement scheme is also included to detect and isolate the misbehaving nodes. By simulation results, we show that the proposed approach reduces the overhead.
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.
LSR PROTOCOL BASED ON NODES POTENTIALITY IN TRUST AND RESIDUAL ENERGY FOR WSNSIJNSA Journal
In Wireless Sensor Networks (WSNs), all the nodes selected for packet routing must be trustworthy, and at the same time energetic too. Smooth conservation of nodes energies and the trust levels, are an important issues in WSN because they directly affects the life span and reliability of the nodes as well as the entire network. The energy utilization at every node must be very smooth and at the same time, packets should be forwarded via trusted nodes only. In this paper, we propose an Energy Efficient Link State Routing Protocol (EELSRP) using the potential nodes selected by applying the fuzzy logic on the trust and residual energy levels. This routing protocol finds the best route by balancing the nodesresidual energies and trust levels, and protects the WSN against routing attacks by eliminating the untrusted nodes before the creation of route.

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.
A Study on Security in Wireless Sensor Networksijtsrd
Wireless Sensor Networks (WSNs) present myriad application opportunities for several applications such as precision agriculture, environmental and habitat monitoring, traffic control, industrial process monitoring and control, home automation and mission-critical surveillance applications such as military surveillance, healthcare (elderly, home monitoring) applications, disaster relief and management, fire detection applications among others. Since WSNs are used in mission-critical tasks, security is an essential requirement. Sensor nodes can easily be compromised by an adversary due to unique constraints inherent in WSNs such as limited sensor node energy, limited computation and communication capabilities and the hostile deployment environments.

ENERGY CONSUMPTION IN WIRELESS SENSOR NETWORKS USING DATA FUSION ASSURANCEijwmn
Data fusion techniques reduce total network traffic in a wireless sensor network, since data fusion can
integrate multiple raw data sets into one fused data set. However, the security or assurance of the data
requires more processing power and is an important issue. Increasing the security of the fusion data
increases factors such as power consumption, and packet overhead. Therefore any data fusion assurance
scheme must be power efficient as well as secure. There are currently several methods of data fusion
assurance that have been proposed. Therefore, this paper looks at the current data fusion assurance
methods and proposes new schemes focused on reducing power consumption. In this paper, several data
fusion assurance schemes are also compared to determine which scheme is the most energy efficient.

integrate multiple raw data sets into one fused data set. However, the security or assurance of the data
requires more processing power and is an important issue. Increasing the security of the fusion data
increases factors such as power consumption, and packet overhead. Therefore any data fusion assurance
scheme must be power efficient as well as secure. There are currently several methods of data fusion
assurance that have been proposed. Therefore, this paper looks at the current data fusion assurance
methods and proposes new schemes focused on reducing power consumption. In this paper, several data
fusion assurance schemes are also compared to determine which scheme is the most energy efficient.

Improving Network Security in MANETS using IEEACKijsrd.com
Mobile ad hoc networks (MANETs) have attracted much attention due to their mobility and ease of deployment. However, the wireless and dynamic natures render them more vulnerable to various types of security attacks than the wired networks. The major challenge is to guarantee secure network services. We have identified the inadequate nature of EAACK in scenarios of link breakage, source maliciousness and partial packet dropping and hence we propose an improved algorithm called improved EAACK to tackle the security issues. High mobility of MANET nodes contributes to frequent link breakages in the network, which leads to path failures and route discovery processes. Route discovery is initialized through a broadcast mechanism usually. But, the overheads created through this cannot be neglected. The simulation results show that IEEACK scheme can prevent attacks from malicious nodes and improve the security performance of the whole network, especially in terms of the packet delivery ratio, the average end-to-end delay, the routing packet overhead and detection ratio of malicious nodes.
A Novel Approach To Detect Trustworthy Nodes Using Audit Based Scheme For WSNIJERDJOURNAL
ABSTRACT: In multi-hop ad hoc networks there exists a problem of identifying and isolating misbehaving nodes which refuses to forward packets. Audit-based Misbehavior Detection (AMD) is a comprehensive system that effectively and efficiently isolates both continuous and selective packet droppers. The AMD system integrates reputation management, trustworthy route discovery, and identification of misbehaving nodes based on behavioral audits. Compared to previous methods, AMD evaluates node behavior on a per-packet basis, without employing energy-expensive overhearing techniques or intensive acknowledgment schemes. Moreover, AMD can detect selective dropping attacks even if end-to-end traffic is encrypted and can be applied to multichannel networks or networks consisting of nodes with directional antennas. This work implements the AMD approach by considering the rushing attack. The analysis of the results confirms that AMD based method with rushing attack performs better as compared to the non rushing attack.
Online stream mining approach for clustering network trafficeSAT Journals
Abstract A large number of research have been proposed on intrusion detection system, which leads to the implementation of agent based intelligent IDS (IIDS), Non – intelligent IDS (NIDS), signature based IDS etc. While building such IDS models, learning algorithms from flow of network traffic plays crucial role in accuracy of IDS systems. The proposed work focuses on implementing the novel method to cluster network traffic which eliminates the limitations in existing online clustering algorithms and prove the robustness and accuracy over large stream of network traffic arriving at extremely high rate. We compare the existing algorithm with novel methods to analyse the accuracy and complexity.

Performance and Simulation Study of TheProposed Direct, Indirect Trust Distri...CSEIJJournal
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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A probabilistic misbehavior detection scheme towards efficient trust establishment in delay tolerant networks
1. A Probabilistic Misbehavior Detection Scheme towards
Efficient Trust Establishment in Delay-tolerant Networks
ABSTRACT:
Malicious and selfish behaviors represent a serious threat against routing in
Delay/Disruption Tolerant Networks (DTNs). Due to the unique network
characteristics, designing a misbehavior detection scheme in DTN is regarded as a
great challenge. In this paper, we propose iTrust, a probabilistic misbehavior
detection scheme, for secure DTN routing towards efficient trust establishment.
The basic idea of iTrust is introducing a periodically available Trusted Authority
(TA) to judge the node’s behavior based on the collected routing evidences and
probabilistically checking. We model iTrust as the Inspection Game and use game
theoretical analysis to demonstrate that, by setting an appropriate investigation
probability, TA could ensure the security of DTN routing at a reduced cost. To
further improve the efficiency of the proposed scheme, we correlate detection
probability with a node’s reputation, which allows a dynamic detection probability
determined by the trust of the users. The extensive analysis and simulation results
show that the proposed scheme substantiates the effectiveness and efficiency of the
proposed scheme.
2. EXISTING SYSTEM:
In DTNs, a node could misbehave by dropping packets intentionally even when it
has the capability to forward the data (e.g., sufficient buffers and meeting
opportunities). Routing misbehavior can be caused by selfish (or rational) nodes
that try to maximize their own benefits by enjoying the services provided by DTN
while refusing to forward the bundles for others, or malicious nodes that drop
packets or modifying the packets to launch attacks.
Recently, there are quite a few proposals for misbehaviors detection in DTNs, most
of which are based on forwarding history verification (e.g., multi-layered credit,
three-hop feedback mechanism, or encounter ticket), which are costly in terms of
transmission overhead and verification cost. The security overhead incurred by
forwarding history checking is critical for a DTN since expensive security
operations will be translated into more energy consumptions, which represents a
fundamental challenge in resource constrained DTN.
DISADVANTAGES OF EXISTING SYSTEM:
Malicious and selfish behaviors represent a serious threat against routing in
Delay/Disruption Tolerant Networks (DTNs).
Due to the unique network characteristics, designing a misbehavior detection
scheme in DTN is regarded as a great challenge.
3. Even though the existing misbehavior detection schemes work well for the
traditional wireless networks, the unique network characteristics including
lack of contemporaneous path, high variation in network conditions,
difficulty to predict mobility patterns, and long feedback delay, have made
the neighborhood monitoring based misbehavior detection scheme
unsuitable for DTNs
PROPOSED SYSTEM:
In this paper, we propose iTrust, a probabilistic misbehavior detection
scheme, for secure DTN routing towards efficient trust establishment.
The basic idea of iTrust is introducing a periodically available Trusted
Authority (TA) to judge the node’s behavior based on the collected routing
evidences and probabilistically checking.
ADVANTAGES OF PROPOSED SYSTEM:
Reduce the detection overhead effectively.
Improved Security.
Improved Efficiency.
Will reduce transmission overhead incurred by misbehavior detection and
detect the malicious nodes effectively.
