M-EPAR to Improve the Quality of the MANETsIJERA Editor
In MANET, power aware is important challenge issue to improve the communication energy efficiency at individual nodes. We propose modified efficient power aware routing (M-EPAR), a new power aware routing protocol that increases the network lifetime of MANET. Designing a power aware routing algorithm or technique is one of the most important point considered in Mobile Ad Hoc Networks. These nodes are driven by reactive protocols where broadcasting is mandatory to form a path between two nodes. So in case of death of the node resulting out of less battery calls for re-routing. Since many existing techniques focuses on energy aware routing this paper presents combination of energy aware routing merged with link quality determined by packet drop rate. The proposed scheme has outperformed the existing technique in terms of packet delivery ratio, throughput and energy consumption.

This paper presents a generalized optimal placement of Phasor Measurement Units (PMUs) considering power system observability, reliability, Communication Infrastructure (CI), and latency time associated with this CI. Moreover, the economic study for additional new data transmission paths is considered as well as the availability of predefined locations of some PMUs and the preexisting communication devices (CDs) in some buses. Two cases for the location of the Control Center Base Station (CCBS) are considered; predefined case and free selected case. The PMUs placement and their required communication network topology and channel capacity are co-optimized simultaneously. In this study, two different approaches are applied to optimize the objective function; the first approach is combined from Binary Particle Swarm Optimization-Gravitational Search Algorithm (BPSOGSA) and the Minimum Spanning Tree (MST) algorithm, while the second approach is based only on BPSOGSA. The feasibility of the proposed approaches are examined by applying it to IEEE 14-bus and IEEE 118-bus systems.

Performance evaluation of interference aware topology power and flow control ...IJECEIAES
Multi-Radio Multi-Channel Wireless Mesh Network (MRMC-WMN) has been considered as one of the key technology for the enhancement of network performance. It is used in a number of real-time applications such as disaster management system, transportation system and health care system. MRMC-WMN is a multi-hop network and allows simultaneous data transfer by using multiple radio interfaces. All the radio interfaces are typically assigned with different channels to reduce the effect of co-channel interference. In MRMC-WMN, when two nodes transmit at the same channel in the range of each other, generates co-channel interference and degrades the network throughput. Co-channel interference badly affects the capacity of each link that reduces the overall network performance. Thus, the important task of channel assignment algorithm is to reduce the co-channel interference and enhance the network performance. In this paper, the problem of channel assignment has been addressed for MRMC-WMN. We have proposed an Interference Aware, Topology, Power and Flow Control (ITPFC) Channel Assignment algorithm for MRMC-WMN. This algorithm assignes the suitable channels to nodes, which provides better link capacity and reduces the co-channel interference. In the previous work performance of the proposed algorithm has been evaluated for a network of 30 nodes. The aim of this paper is to further evaluate the performance of proposed channel assignment algorithm for 40 and 50 nodes network. The results obtained from these networks show the consistent performance in terms of throughput, delay, packet loss and number of channels used per node as compared to LACA, FCPRA and IATC Channel Assignment algorithms.

Optimized Cluster Establishment and Cluster-Head Selection Approach in WSNIJCNCJournal
In recent years, limited resources of user products and energy-saving are recognized as the major challenges of Wireless Sensor Networks (WSNs). Clustering is a practical technique that can reduce all energy consumption and provide stability of workload that causes a larger difference in energy depletion among other nodes and cluster heads (CHs). In addition, clustering is the solution of energy-efficient for maximizing the network longevity and improvising energy efficiency. In this paper, a novel OCE-CHS (Optimized Cluster Establishment and Cluster-Head Selection) approach for sensor nodes is represented to improvise the packet success ratio and reduce the average energy-dissipation. The main contribution of this paper is categorized into two processes, first, the clustering algorithm is improvised that periodically chooses the optimal set of the CHs according to the speed of the average node and average-node energy. This is considerably distinguished from node-based clustering that utilizes a distributed clustering algorithm to choose CHs based on the speed of the current node and remaining node energy. Second, more than one factor is assumed for the detached node to join the optimal cluster. In the result section, we discuss our clustering protocols implementation of optimal CH-selection to evade the death of SNs, maximizing throughput, and further improvise the network lifetime by minimizing energy consumption.
Q-LEARNING BASED ROUTING PROTOCOL TO ENHANCE NETWORK LIFETIME IN WSNSIJCNCJournal
In resource constraint Wireless Sensor Networks (WSNs), enhancement of network lifetime has been one of the significantly challenging issues for the researchers. Researchers have been exploiting machine learning techniques, in particular reinforcement learning, to achieve efficient solutions in the domain of WSN. The objective of this paper is to apply Q-learning, a reinforcement learning technique, to enhance the lifetime of the network, by developing distributed routing protocols. Q-learning is an attractive choice for routing due to its low computational requirements and additional memory demands. To facilitate an agent running at each node to take an optimal action, the approach considers node’s residual energy, hop length to sink and transmission power. The parameters, residual energy and hop length, are used to calculate the Q-value, which in turn is used to decide the optimal next-hop for routing. The proposed protocols’ performance is evaluated through NS3 simulations, and compared with AODV protocol in terms of network lifetime, throughput and end-to-end delay.
The maximization of a networks lifetime is an important part of research in the present scenario. In ad hoc network, the topology of network changes frequently due to the mobility of mobile nodes where the communication is possible without any network infrastructure. Mobile nodes have limited energy resources so that the energy efficient routing should be provided which increases the life time of the network. The existing routing mechanisms do not consider energy of nodes for data transmission. In this paper a novel approach is analyzed to improve the networks lifetime where the data transfer is based on the minimum hop count and residual energy of the mobile nodes. The analysis is carried out by using the network simulator and the simulation results shows that the proposed work provides an energy efficient routing in ad hoc networks.
An Efficient and Stable Routing Algorithm in Mobile Ad Hoc NetworkIJCNCJournal
Mobile Ad hoc Network (MANET) is mainly designed to set up communication among devices in infrastructure-less wireless communication network. Routing in this kind of communication network is highly affected by its restricted characteristics such as frequent topological changes and limited battery power. Several research works have been carried out to improve routing performance in MANET. However, the overall performance enhancement in terms of packet delivery, delay and control message overhead is still not come into the wrapping up. In order to overcome the addressed issues, an Efficient and Stable-AODV (EFST-AODV) routing scheme has been proposed which is an improvement over AODV to establish a better quality route between source and destination. In this method, we have modified the route request and route reply phase. During the route request phase, cost metric of a route is calculated on the basis of parameters such as residual energy, delay and distance. In a route reply phase, average residual energy and average delay of overall path is calculated and the data forwarding decision is taken at the source node accordingly. Simulation outcomes reveal that the proposed approach gives better results in terms of packet delivery ratio, delay, throughput, normalized routing load and control message overhead as compared to AODV.
A RELIABLE AND ENERGY EFFICIENCT ROUTING PROTOCOL FOR MANETs cscpconf
A mobile ad-hoc network (MANETs) is an infrastructure less network in which the mobile nodes
communicate with each other. Due to its various characteristics like highly dynamic topology
and limited battery power of the nodes, routing is one of the key issue. Also, it is not possible to
give a significant amount of power to the mobile nodes of ad-hoc networks. Because of all this
the energy consumption is also an important issue. Due to limited battery power, some other
issues like if some node gets fail, which results in loss of data packets and no reliable data
transfer has been raised. In this paper, an algorithm is proposed for data transmission which
detects the node failure (due to energy) before it actually happens. Because of this network
lifetime gets improved. The proposed routing algorithm is energy efficient as compared to
AODV routing algorithm. The performance is analyzed on the basis of various performance
metrics like Energy Consumption, Packet Delivery Ratio, Network Life Time, Network Routing
Overhead and number of Exhausted nodes in the network by using the NS2 Simulator.
Performance evaluation of MANET routing protocols based on QoS and energy p...IJECEIAES
Routing selection and supporting Quality of Service (QoS) are fundamental problems in Mobile Ad Hoc Network (MANET). Many different protocols have been proposed in the literature and some performance simulations are made to address this challenging task. This paper discusses the performance evaluation and comparison of two typical routing protocols; Ad Hoc On-Demand Distance Vector (AODV) and Destination-Sequenced DistanceVector (DSDV) based on measuring the power consumption in network with varing of the QoS parameters. In this paper, we have studied and analyzed the impact of variations in QoS parameter combined with the choice of routing protocol, on network performance. The network performance is measured in terms of average throughput, packet delivery ratio (PDR), average jitter and energy consumption. The simulations are carried out in NS-3. The simulation results show that DSDV and AODV routing protocols are less energy efficient. The main aim of this paper is to highlight the directions for the future design of routing protocol which would be better than the existing ones in terms of energy utilization and delivery ratio.

Ant-colony and nature-inspired heuristic models for NOMA systems: a reviewTELKOMNIKA JOURNAL
The increasing computational complexity in scheduling the large number of users for non-orthogonal multiple access (NOMA) system and future cellular networks lead to the need for scheduling models with relatively lower computational complexity such as heuristic models. The main objective of this paper is to conduct a concise study on ant-colony optimization (ACO) methods and potential nature-inspired heuristic models for NOMA implementation in future high-speed networks. The issues, challenges and future work of ACO and other related heuristic models in NOMA are concisely reviewed. The throughput result of the proposed ACO method is observed to be close to the maximum theoretical value and stands 44% higher than that of the existing method. This result demonstrates the effectiveness of ACO implementation for NOMA user scheduling and grouping.
Address-light and energy aware routing protocol for wireless sensor networkTELKOMNIKA JOURNAL
In recent years, sensor networks applications were used in many criteria. Because of its vast applications, so many researchers studied these networks. Wireless sensor networks contain significant number of sensor nodes; they are suitable medium for collecting and sending data or informing the sink about an event. This study presents a new integrated method for routing in sensor networks which is based on remaining energy of the nodes and existing space between each node and the sink. This method is more suitable for large and medium volume of data. Lifetime enhancement of the network is the main purpose of this method which is obtained by fair division of nodes roles in transmission of data to the sink. In ALERP algorithm (Address Light, Label-Based and Energy-Aware Routing Protocol), in order to reduce network overload and energy consuming as well as enhancement of network lifetime, we used predetermined routes as well as routing based on packet labels. Energy consumption in the entire network is another advantage of this method. The existence of various parameters on this algorithm will lead to more flexibility of it. Generally, conducted simulations indicate higher uniformity in energy consumption of nodes.

Nowadays, Vehicular Ad-Hoc Network (VANET) has got more attention from the researchers. The researchers have studied numerous topics of VANET, such as the routing protocols of VANET and the MAC protocols of VANET. The aim of their works is to improve the network performance of VANET, either in terms of energy consumption or packet delivery ratio (PDR) and delay. For this research paper, the main goal is to find the coefficient of a, b and c of three non-linear equations by using a Newton- Raphson method. Those three non-linear equations are derived from a different value of Medium Access Control (MAC) protocol's parameters. After that, those three coefficient is then will be used in optimization of the VANET in terms of energy, PDR, and delay.
Traffic Congestion Prediction using Deep Reinforcement Learning in Vehicular ...IJCNCJournal
In recent years, a new wireless network called vehicular ad-hoc network (VANET), has become a popular research topic. VANET allows communication among vehicles and with roadside units by providing information to each other, such as vehicle velocity, location and direction. In general, when many vehicles likely to use the common route to proceed to the same destination, it can lead to a congested route that should be avoided. It may be better if vehicles are able to predict accurately the traffic congestion and then avoid it. Therefore, in this work, the deep reinforcement learning in VANET to enhance the ability to predict traffic congestion on the roads is proposed. Furthermore, different types of neural networks namely Convolutional Neural Network (CNN), Multilayer Perceptron (MLP) and Long Short-Term Memory (LSTM) are investigated and compared in this deep reinforcement learning model to discover the most effective one. Our proposed method is tested by simulation. The traffic scenarios are created using traffic simulator called Simulation of Urban Mobility (SUMO) before integrating with deep reinforcement learning model. The simulation procedures, as well as the programming used, are described in detail. The performance of our proposed method is evaluated using two metrics; the average travelling time delay and average waiting time delay of vehicles. According to the simulation results, the average travelling time delay and average waiting time delay are gradually improved over the multiple runs, since our proposed method receives feedback from the environment. In addition, the results without and with three different deep learning algorithms, i.e., CNN, MLP and LSTM are compared. It is obvious that the deep reinforcement learning model works effectively when traffic density is neither too high nor too low. In addition, it can be concluded that the effective algorithms for traffic congestion prediction models in descending order are MLP, CNN, and LSTM, respectively.
A scalable and power efficient solution for routing in mobile ad hoc network ...ijmnct
Mobile Ad Hoc Network (MANET) is a very dynamic and infrastructure-less ad hoc network. The actual
network size depends on the application and the protocols developed for the routing for this kind of
networks should be scalable. MANET is a resource limited network and therefore the developed routing
algorithm for packet transmission should be power and bandwidth efficient. These kinds of dynamic
networks should operate with minimal management overhead. The management functionality of the
network increases with number of nodes and reduces the performance of the network. Here, in this paper,
we have designed all identical nodes in the cluster except the cluster head and this criterion reduces the
management burden on the network. Graph theoretic routing algorithm is used to develop route for packet
transmission by using the minimum resources. In this paper, we developed routing algorithm for cluster
based MANET and finds a path from source to destination using minimum cumulative degree path. Our
simulation results show that this routing algorithm provide efficient routing path with the increasing
number of nodes and uses multi-hop connectivity for intra-cluster to utilize minimum power for packet
transmission irrespective of number of nodes in the network.
ENERGY EFFICIENT ROUTING PROTOCOL BASED ON DSRijasuc
Energy consumption is a major concern in most of the present day devices in wireless networks. Especially
in Ad hoc networks, energy is a limited factor. Random movement in nodes add to the frequent failure of
routes which adds to the energy consumption in the network. In this paper, a routing protocol is proposed
which is based on a modification of the conventional DSR (Dynamic Source routing). A comparative
analysis is performed with respect to energy consumption, maximum throughput and delay. The routing
protocols used for reference in this analysis are DSDV, AODV and conventional DSR. Experimental results
show that the proposed modified DSR shows a reduced energy consumption, improved rate of maximum
throughput and a reduced delay compared to above mentioned routing protocols
Evaluation of Energy Consumption of Reactive and Proactive Routing Protocols ...IJCNCJournal
Mobile Ad hoc Network (MANET) is a distributed, infrastructure-less and decentralized network. A routing
protocol in MANET is used to find routes between mobile nodes to facilitate communication within the
network. Numerous routing protocols have been proposed for MANET. Those routing protocols are
designed to adaptively accommodate for dynamic unpredictable changes in network's topology. The mobile
nodes in MANET are often powered by limited batteries and network lifetime relies heavily on the energy
consumption of nodes. In consequence, the lack of a mobile node can lead to network partitioning. In this
paper we analyse, evaluate and measure the energy efficiency of three prominent MANET routing protocols
namely DSR, AODV and OLSR in addition to modified protocols. These routing protocols follow the
reactive and the proactive routing schemes. A discussion and comparison highlighting their particular
merits and drawbacks are also presented. Evaluation study and simulations are performed using NS-2 and
its accompanying tools for analysis and investigation of results.
Performance Evaluation of Consumed Energy-Type-Aware Routing (CETAR) For Wire...ijwmn
This work evaluates the performance of Consumed-Energy-Type-Aware Routing (CETAR) which incorporates the amount of energy consumed per type of operation for routing decision to extend the lifetime of the Wireless Sensor Networks (WSNs). CETAR makes routing decision using statistics of the energy consumed for each type of node activities including sensing, data processing, data transmission as a source node, and routing operations. In particular, CETAR encourages a node which seldom plays a role of source node as a routing node to preserve the energy of active source nodes to prolong the functionality of the WSNs. Extensive simulation study demonstrates that the lifetime of the Geographic and Energy Aware Routing (GEAR) can be significantly extended with CETAR. With its adaptability to deployed sensor node behaviors, the significance of CETAR to extend the lifetime of WSNs is clear.

MATLAB-7.01. The routing protocol used in our simulation is Minimum Total Power Routing (MTPR) and
different performance metrics such as path optimality, throughput and hop count were recorded in
presence and absence of power scarce node. The result shows significant impact of power scarce node on
MANET performance.

It explains an innovative multicasting algorithm that considers the transmission energy and residual energy while forwarding the data packets. It improves the network throughput and raises the network lifetimes. Simulation analysis is carried in this proposed system and this method shows improved performance over the existing system.
PERFORMANCE OF OLSR MANET ADOPTING CROSS-LAYER APPROACH UNDER CBR AND VBR TRA...IJCNCJournal
The routing protocols play an important role in Mobile Ad-Hoc Network (MANET) because of the dynamically change of its topology. Optimized Link State Routing (OLSR), unawareness of Quality of Service (QoS) and power-consumed protocol, is an example of a widely-used routing protocol in MANET.
The Multi-Point Relays (MPR) selection algorithm is very crucial in OLSR. Therefore, firstly, we propose a heuristic method to select the best path based on two parameters; Bit Error Rate (BER) derived from the physical layer and Weighted Connectivity Index (CI) adopted from the network layer. This can be done via the cross-layer design scheme. This is anticipated to enhance the performance of OLSR, provide QoS
guarantee and improve the power consumption. The performances of the proposed scheme are investigated
by simulation of two types of traffics: CBR and VBR (MPEG-4), evaluated by metrics namely Throughput, Packet Delivery Ratio (PDR), Average End-to-End Delay, Control Overhead and Average Total Power Consumption.We compare our results with the typical OLSR and OLSR using only Weighted CI. It is
obvious that our proposed scheme provides superior performances to the typical OLSR and OLSR using only Weighted CI, especially, at high traffic load.

The objective of this paper is to apply Q-learning, a reinforcement learning technique, to enhance the lifetime of the network, by developing distributed routing protocols. Q-learning is an attractive choice for routing due to its low computational requirements and additional memory demands. To facilitate an agent running at each node to take an optimal action, the approach considers node’s residual energy, hop length to sink and transmission power. The parameters, residual energy and hop length, are used to calculate the Q-value, which in turn is used to decide the optimal next-hop for routing. The proposed protocols’ performance is evaluated through NS3 simulations, and compared with AODV protocol in terms of network lifetime, throughput and end-to-end delay.
The maximization of a networks lifetime is an important part of research in the present scenario. In ad hoc network, the topology of network changes frequently due to the mobility of mobile nodes where the communication is possible without any network infrastructure. Mobile nodes have limited energy resources so that the energy efficient routing should be provided which increases the life time of the network. The existing routing mechanisms do not consider energy of nodes for data transmission. In this paper a novel approach is analyzed to improve the networks lifetime where the data transfer is based on the minimum hop count and residual energy of the mobile nodes. The analysis is carried out by using the network simulator and the simulation results shows that the proposed work provides an energy efficient routing in ad hoc networks.
An Efficient and Stable Routing Algorithm in Mobile Ad Hoc NetworkIJCNCJournal
Mobile Ad hoc Network (MANET) is mainly designed to set up communication among devices in infrastructure-less wireless communication network. Routing in this kind of communication network is highly affected by its restricted characteristics such as frequent topological changes and limited battery power. Several research works have been carried out to improve routing performance in MANET. However, the overall performance enhancement in terms of packet delivery, delay and control message overhead is still not come into the wrapping up. In order to overcome the addressed issues, an Efficient and Stable-AODV (EFST-AODV) routing scheme has been proposed which is an improvement over AODV to establish a better quality route between source and destination. In this method, we have modified the route request and route reply phase. During the route request phase, cost metric of a route is calculated on the basis of parameters such as residual energy, delay and distance. In a route reply phase, average residual energy and average delay of overall path is calculated and the data forwarding decision is taken at the source node accordingly. Simulation outcomes reveal that the proposed approach gives better results in terms of packet delivery ratio, delay, throughput, normalized routing load and control message overhead as compared to AODV.
A RELIABLE AND ENERGY EFFICIENCT ROUTING PROTOCOL FOR MANETs cscpconf
A mobile ad-hoc network (MANETs) is an infrastructure less network in which the mobile nodes
communicate with each other. Due to its various characteristics like highly dynamic topology
and limited battery power of the nodes, routing is one of the key issue. Also, it is not possible to
give a significant amount of power to the mobile nodes of ad-hoc networks. Because of all this
the energy consumption is also an important issue. Due to limited battery power, some other
issues like if some node gets fail, which results in loss of data packets and no reliable data
transfer has been raised. In this paper, an algorithm is proposed for data transmission which
detects the node failure (due to energy) before it actually happens. Because of this network
lifetime gets improved. The proposed routing algorithm is energy efficient as compared to
AODV routing algorithm. The performance is analyzed on the basis of various performance
metrics like Energy Consumption, Packet Delivery Ratio, Network Life Time, Network Routing
Overhead and number of Exhausted nodes in the network by using the NS2 Simulator.
Performance evaluation of MANET routing protocols based on QoS and energy p...IJECEIAES
Routing selection and supporting Quality of Service (QoS) are fundamental problems in Mobile Ad Hoc Network (MANET). Many different protocols have been proposed in the literature and some performance simulations are made to address this challenging task. This paper discusses the performance evaluation and comparison of two typical routing protocols; Ad Hoc On-Demand Distance Vector (AODV) and Destination-Sequenced DistanceVector (DSDV) based on measuring the power consumption in network with varing of the QoS parameters. In this paper, we have studied and analyzed the impact of variations in QoS parameter combined with the choice of routing protocol, on network performance. The network performance is measured in terms of average throughput, packet delivery ratio (PDR), average jitter and energy consumption. The simulations are carried out in NS-3. The simulation results show that DSDV and AODV routing protocols are less energy efficient. The main aim of this paper is to highlight the directions for the future design of routing protocol which would be better than the existing ones in terms of energy utilization and delivery ratio.

Ant-colony and nature-inspired heuristic models for NOMA systems: a reviewTELKOMNIKA JOURNAL
The increasing computational complexity in scheduling the large number of users for non-orthogonal multiple access (NOMA) system and future cellular networks lead to the need for scheduling models with relatively lower computational complexity such as heuristic models. The main objective of this paper is to conduct a concise study on ant-colony optimization (ACO) methods and potential nature-inspired heuristic models for NOMA implementation in future high-speed networks. The issues, challenges and future work of ACO and other related heuristic models in NOMA are concisely reviewed. The throughput result of the proposed ACO method is observed to be close to the maximum theoretical value and stands 44% higher than that of the existing method. This result demonstrates the effectiveness of ACO implementation for NOMA user scheduling and grouping.
Address-light and energy aware routing protocol for wireless sensor networkTELKOMNIKA JOURNAL
In recent years, sensor networks applications were used in many criteria. Because of its vast applications, so many researchers studied these networks. Wireless sensor networks contain significant number of sensor nodes; they are suitable medium for collecting and sending data or informing the sink about an event. This study presents a new integrated method for routing in sensor networks which is based on remaining energy of the nodes and existing space between each node and the sink. This method is more suitable for large and medium volume of data. Lifetime enhancement of the network is the main purpose of this method which is obtained by fair division of nodes roles in transmission of data to the sink. In ALERP algorithm (Address Light, Label-Based and Energy-Aware Routing Protocol), in order to reduce network overload and energy consuming as well as enhancement of network lifetime, we used predetermined routes as well as routing based on packet labels. Energy consumption in the entire network is another advantage of this method. The existence of various parameters on this algorithm will lead to more flexibility of it. Generally, conducted simulations indicate higher uniformity in energy consumption of nodes.

Nowadays, Vehicular Ad-Hoc Network (VANET) has got more attention from the researchers. The researchers have studied numerous topics of VANET, such as the routing protocols of VANET and the MAC protocols of VANET. The aim of their works is to improve the network performance of VANET, either in terms of energy consumption or packet delivery ratio (PDR) and delay. For this research paper, the main goal is to find the coefficient of a, b and c of three non-linear equations by using a Newton- Raphson method. Those three non-linear equations are derived from a different value of Medium Access Control (MAC) protocol's parameters. After that, those three coefficient is then will be used in optimization of the VANET in terms of energy, PDR, and delay.
Traffic Congestion Prediction using Deep Reinforcement Learning in Vehicular ...IJCNCJournal
In recent years, a new wireless network called vehicular ad-hoc network (VANET), has become a popular research topic. VANET allows communication among vehicles and with roadside units by providing information to each other, such as vehicle velocity, location and direction. In general, when many vehicles likely to use the common route to proceed to the same destination, it can lead to a congested route that should be avoided. It may be better if vehicles are able to predict accurately the traffic congestion and then avoid it. Therefore, in this work, the deep reinforcement learning in VANET to enhance the ability to predict traffic congestion on the roads is proposed. Furthermore, different types of neural networks namely Convolutional Neural Network (CNN), Multilayer Perceptron (MLP) and Long Short-Term Memory (LSTM) are investigated and compared in this deep reinforcement learning model to discover the most effective one. Our proposed method is tested by simulation. The traffic scenarios are created using traffic simulator called Simulation of Urban Mobility (SUMO) before integrating with deep reinforcement learning model. The simulation procedures, as well as the programming used, are described in detail. The performance of our proposed method is evaluated using two metrics; the average travelling time delay and average waiting time delay of vehicles. According to the simulation results, the average travelling time delay and average waiting time delay are gradually improved over the multiple runs, since our proposed method receives feedback from the environment. In addition, the results without and with three different deep learning algorithms, i.e., CNN, MLP and LSTM are compared. It is obvious that the deep reinforcement learning model works effectively when traffic density is neither too high nor too low. In addition, it can be concluded that the effective algorithms for traffic congestion prediction models in descending order are MLP, CNN, and LSTM, respectively.
A scalable and power efficient solution for routing in mobile ad hoc network ...ijmnct
Mobile Ad Hoc Network (MANET) is a very dynamic and infrastructure-less ad hoc network. The actual
network size depends on the application and the protocols developed for the routing for this kind of
networks should be scalable. MANET is a resource limited network and therefore the developed routing
algorithm for packet transmission should be power and bandwidth efficient. These kinds of dynamic
networks should operate with minimal management overhead. The management functionality of the
network increases with number of nodes and reduces the performance of the network. Here, in this paper,
we have designed all identical nodes in the cluster except the cluster head and this criterion reduces the
management burden on the network. Graph theoretic routing algorithm is used to develop route for packet
transmission by using the minimum resources. In this paper, we developed routing algorithm for cluster
based MANET and finds a path from source to destination using minimum cumulative degree path. Our
simulation results show that this routing algorithm provide efficient routing path with the increasing
number of nodes and uses multi-hop connectivity for intra-cluster to utilize minimum power for packet
transmission irrespective of number of nodes in the network.
ENERGY EFFICIENT ROUTING PROTOCOL BASED ON DSRijasuc
Energy consumption is a major concern in most of the present day devices in wireless networks. Especially
in Ad hoc networks, energy is a limited factor. Random movement in nodes add to the frequent failure of
routes which adds to the energy consumption in the network. In this paper, a routing protocol is proposed
which is based on a modification of the conventional DSR (Dynamic Source routing). A comparative
analysis is performed with respect to energy consumption, maximum throughput and delay. The routing
protocols used for reference in this analysis are DSDV, AODV and conventional DSR. Experimental results
show that the proposed modified DSR shows a reduced energy consumption, improved rate of maximum
throughput and a reduced delay compared to above mentioned routing protocols
Evaluation of Energy Consumption of Reactive and Proactive Routing Protocols ...IJCNCJournal
Mobile Ad hoc Network (MANET) is a distributed, infrastructure-less and decentralized network. A routing
protocol in MANET is used to find routes between mobile nodes to facilitate communication within the
network. Numerous routing protocols have been proposed for MANET. Those routing protocols are
designed to adaptively accommodate for dynamic unpredictable changes in network's topology. The mobile
nodes in MANET are often powered by limited batteries and network lifetime relies heavily on the energy
consumption of nodes. In consequence, the lack of a mobile node can lead to network partitioning. In this
paper we analyse, evaluate and measure the energy efficiency of three prominent MANET routing protocols
namely DSR, AODV and OLSR in addition to modified protocols. These routing protocols follow the
reactive and the proactive routing schemes. A discussion and comparison highlighting their particular
merits and drawbacks are also presented. Evaluation study and simulations are performed using NS-2 and
its accompanying tools for analysis and investigation of results.
Performance Evaluation of Consumed Energy-Type-Aware Routing (CETAR) For Wire...ijwmn
This work evaluates the performance of Consumed-Energy-Type-Aware Routing (CETAR) which incorporates the amount of energy consumed per type of operation for routing decision to extend the lifetime of the Wireless Sensor Networks (WSNs). CETAR makes routing decision using statistics of the energy consumed for each type of node activities including sensing, data processing, data transmission as a source node, and routing operations. In particular, CETAR encourages a node which seldom plays a role of source node as a routing node to preserve the energy of active source nodes to prolong the functionality of the WSNs. Extensive simulation study demonstrates that the lifetime of the Geographic and Energy Aware Routing (GEAR) can be significantly extended with CETAR. With its adaptability to deployed sensor node behaviors, the significance of CETAR to extend the lifetime of WSNs is clear.

Power conservation in Mobile Ad hoc Network (MANET) is a major challenge even today for researchers.
To conserve it various power aware routing protocols have been proposed. These protocols do not take into

MATLAB-7.01. The routing protocol used in our simulation is Minimum Total Power Routing (MTPR) and
different performance metrics such as path optimality, throughput and hop count were recorded in
presence and absence of power scarce node. The result shows significant impact of power scarce node on
MANET performance.

PERFORMANCE OF OLSR MANET ADOPTING CROSS-LAYER APPROACH UNDER CBR AND VBR TRA...IJCNCJournal
The routing protocols play an important role in Mobile Ad-Hoc Network (MANET) because of the dynamically change of its topology. Optimized Link State Routing (OLSR), unawareness of Quality of Service (QoS) and power-consumed protocol, is an example of a widely-used routing protocol in MANET.
The Multi-Point Relays (MPR) selection algorithm is very crucial in OLSR. Therefore, firstly, we propose a heuristic method to select the best path based on two parameters; Bit Error Rate (BER) derived from the physical layer and Weighted Connectivity Index (CI) adopted from the network layer. This can be done via the cross-layer design scheme. This is anticipated to enhance the performance of OLSR, provide QoS
guarantee and improve the power consumption. The performances of the proposed scheme are investigated
by simulation of two types of traffics: CBR and VBR (MPEG-4), evaluated by metrics namely Throughput, Packet Delivery Ratio (PDR), Average End-to-End Delay, Control Overhead and Average Total Power Consumption.We compare our results with the typical OLSR and OLSR using only Weighted CI. It is
obvious that our proposed scheme provides superior performances to the typical OLSR and OLSR using only Weighted CI, especially, at high traffic load.

MPR selection powered by (WFS) algorithm leads to decreasing MPR count required to cover 95% of
mobile nodes, increasing throughput , and decreasing topology control which mitigates broadcasting storm
phenomenon in VANETs.

Energy consumption is a significant issue in ad hoc networks since mobile nodes are battery powered. In
order to prolong the lifetime of ad hoc networks, it is the most critical issue to minimize the energy

show that the proposed routing protocol with transmission power and residual energy control mode can
extend the life-span of network and can achieve higher performance when compared to traditional ad-hoc

Multipoint Relay Path for Efficient Topology Maintenance Algorithm in Optimiz...IJCNCJournal
The Optimal Link State Routing (OLSR) protocol employs multipoint relay (MPR) nodes to disseminate topology control (TC) messages, enabling network topology discovery and maintenance. However, this approach increases control overhead and leads to wasted network bandwidth in stable topology scenarios due to fixed flooding periods. To address these challenges, this paper presents an Efficient Topology Maintenance Algorithm (ETM-OLSR) for Enhanced Link-State Routing Protocols. By reducing the number of MPR nodes, TC message generation and forwarding frequency are minimized. Furthermore, the algorithm selects a smaller subset of TC messages based on the changes in the MPR selection set from the previous cycle, adapting to stable and fluctuating network conditions. Additionally, the sending cycle of TC messages is dynamically adjusted in response to network topology changes. Simulation results demonstrate that the ETM-OLSR algorithm effectively reduces network control overhead, minimizes end-to-end delay, and improves network throughput compared to traditional OLSR and HTR-OLSR algorithms.

Mobile ad-hoc network (MANET) is a set of mobile wireless nodes (devices) which is not rely on a fixed infrastructure. In MANETs, each device is responsible for routing its data according to a specific routing protocol. The three most common MANET routing protocols are: dynamic source routing protocol (DSR), optimized link state routing protocol (OLSR), and ad-hoc on-demand distance vector (AODV). This paper proposes an efficient evaluation of DSR protocol by testing the MANETs routing protocol with variation in transmission power at different speeds. The performance analysis has been given using optimized network engineering tools (OPNET) modeler simulations and evaluated using metrics of average end to end delay and throughput. The results show that the throughput increases as the transmission power increases up to a certain value after which the throughput decreases, also the network work optimally at a certain transmission power which varied at different speed.

One of the most important issues discussed in Wireless Sensor Networks (WSNs) is how to transfer information from nodes within the network to the base station and select the best possible route for transmission of this information, taking into account energy consumption for the network lifetime with
maximum reliability and security. Hence, it would be useful to provide a suitable method that would have the features mentioned. This paper uses an Ad-hoc On-demand Multipath Distance Vector (AOMDV) as a routing protocol. This protocol has high energy consumption due to its multipath. However, it is a big challenge if it can reduce AOMDV energy consumption. Therefore, clustering operations for nodes are of high priority to determine the head of clusters which LEACH protocol and fuzzy logic and Particle Swarm Optimization (PSO) algorithm are used for this purpose. Simulation results represent 5% improvement in energy consumption in a WSN compared to AOMDV method.

CONTEXT-AWARE ENERGY CONSERVING ROUTING ALGORITHM FOR INTERNET OF THINGSIJCNCJournal
Internet of Things (IoT) is the fast- growing technology, mostly used in smart mobile devices such as notebooks, tablets, personal digital assistants (PDA), smartphones, etc. Due to its dynamic nature and the limited battery power of the IoT enabled smart mobile nodes, the communication links between intermediate relay nodes may fail frequently, thus affecting the routing performance of the network and also the availability of the nodes. Existing algorithm does not concentrate about communication links and battery power/energy, but these node links are a very important factor for improving the quality of routing in IoT. In this paper, Context-aware Energy Conserving Algorithm for routing (CECA) was proposed which employs QoS routing metrics like Inter-Meeting Time and residual energy and has been applied to IoT enabled smart mobile devices using different technologies with different microcontroller which resulted in an increased network lifetime, throughput and reduced control overhead and the end to end delay. Simulation results show that, with respect to the speed of the mobile nodes from 2 to 10m/s, CECA increases the network lifetime, thereby increasing the average residual energy by 11.1% and increasing throughput there by reduces the average end to end delay by 14.1% over the Energy-Efficient Probabilistic Routing (EEPR) algorithm. With respect to the number of nodes increases from 10 to 100 nodes, CECA algorithms increase the average residual energy by16.1 % reduces the average end to end delay by 15.9% and control overhead by 23.7% over the existing EEPR

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.

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

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

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.

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.
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%.

This research is developing an incubator system that integrates the internet of things and artificial intelligence to improve care for premature babies. The system workflow starts with sensors that collect data from the incubator. Then, the data is sent in real-time to the internet of things (IoT) broker eclipse mosquito using the message queue telemetry transport (MQTT) protocol version 5.0. After that, the data is stored in a database for analysis using the long short-term memory network (LSTM) method and displayed in a web application using an application programming interface (API) service. Furthermore, the experimental results produce as many as 2,880 rows of data stored in the database. The correlation coefficient between the target attribute and other attributes ranges from 0.23 to 0.48. Next, several experiments were conducted to evaluate the model-predicted value on the test data. The best results are obtained using a two-layer LSTM configuration model, each with 60 neurons and a lookback setting 6. This model produces an R 2 value of 0.934, with a root mean square error (RMSE) value of 0.015 and a mean absolute error (MAE) of 0.008. In addition, the R 2 value was also evaluated for each attribute used as input, with a result of values between 0.590 and 0.845.

Honey is produced exclusively by honeybees and stingless bees which both are well adapted to tropical and subtropical regions such as Malaysia. Stingless bees are known for producing small amounts of honey and are known for having a unique flavor profile. Problem identified that many stingless bees collapsed due to weather, temperature and environment. It is critical to understand the relationship between the production of stingless bee honey and environmental conditions to improve honey production.

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.
Fuzzy linear programming with the intuitionistic polygonal fuzzy numbersIJECEIAES
In real world applications, data are subject to ambiguity due to several factors; fuzzy sets and fuzzy numbers propose a great tool to model such ambiguity. In case of hesitation, the complement of a membership value in fuzzy numbers can be different from the non-membership value, in which case we can model using intuitionistic fuzzy numbers as they provide flexibility by defining both a membership and a non-membership functions. In this article, we consider the intuitionistic fuzzy linear programming problem with intuitionistic polygonal fuzzy numbers, which is a generalization of the previous polygonal fuzzy numbers found in the literature. We present a modification of the simplex method that can be used to solve any general intuitionistic fuzzy linear programming problem after approximating the problem by an intuitionistic polygonal fuzzy number with n edges. This method is given in a simple tableau formulation, and then applied on numerical examples for clarity.
The performance of artificial intelligence in prostate magnetic resonance im...IJECEIAES
Prostate cancer is the predominant form of cancer observed in men worldwide. The application of magnetic resonance imaging (MRI) as a guidance tool for conducting biopsies has been established as a reliable and well-established approach in the diagnosis of prostate cancer. The diagnostic performance of MRI-guided prostate cancer diagnosis exhibits significant heterogeneity due to the intricate and multi-step nature of the diagnostic pathway. The development of artificial intelligence (AI) models, specifically through the utilization of machine learning techniques such as deep learning, is assuming an increasingly significant role in the field of radiology. In the realm of prostate MRI, a considerable body of literature has been dedicated to the development of various AI algorithms. These algorithms have been specifically designed for tasks such as prostate segmentation, lesion identification, and classification. The overarching objective of these endeavors is to enhance diagnostic performance and foster greater agreement among different observers within MRI scans for the prostate. This review article aims to provide a concise overview of the application of AI in the field of radiology, with a specific focus on its utilization in prostate MRI.
Seizure stage detection of epileptic seizure using convolutional neural networksIJECEIAES
According to the World Health Organization (WHO), seventy million individuals worldwide suffer from epilepsy, a neurological disorder. While electroencephalography (EEG) is crucial for diagnosing epilepsy and monitoring the brain activity of epilepsy patients, it requires a specialist to examine all EEG recordings to find epileptic behavior. This procedure needs an experienced doctor, and a precise epilepsy diagnosis is crucial for appropriate treatment. To identify epileptic seizures, this study employed a convolutional neural network (CNN) based on raw scalp EEG signals to discriminate between preictal, ictal, postictal, and interictal segments. The possibility of these characteristics is explored by examining how well timedomain signals work in the detection of epileptic signals using intracranial Freiburg Hospital (FH), scalp Children's Hospital Boston-Massachusetts Institute of Technology (CHB-MIT) databases, and Temple University Hospital (TUH) EEG. To test the viability of this approach, two types of experiments were carried out. Firstly, binary class classification (preictal, ictal, postictal each versus interictal) and four-class classification (interictal versus preictal versus ictal versus postictal). The average accuracy for stage detection using CHB-MIT database was 84.4%, while the Freiburg database's time-domain signals had an accuracy of 79.7% and the highest accuracy of 94.02% for classification in the TUH EEG database when comparing interictal stage to preictal stage.
Analysis of driving style using self-organizing maps to analyze driver behaviorIJECEIAES
Modern life is strongly associated with the use of cars, but the increase in acceleration speeds and their maneuverability leads to a dangerous driving style for some drivers. In these conditions, the development of a method that allows you to track the behavior of the driver is relevant. The article provides an overview of existing methods and models for assessing the functioning of motor vehicles and driver behavior. Based on this, a combined algorithm for recognizing driving style is proposed. To do this, a set of input data was formed, including 20 descriptive features: About the environment, the driver's behavior and the characteristics of the functioning of the car, collected using OBD II. The generated data set is sent to the Kohonen network, where clustering is performed according to driving style and degree of danger. Getting the driving characteristics into a particular cluster allows you to switch to the private indicators of an individual driver and considering individual driving characteristics. The application of the method allows you to identify potentially dangerous driving styles that can prevent accidents.
Hyperspectral object classification using hybrid spectral-spatial fusion and ...IJECEIAES
Because of its spectral-spatial and temporal resolution of greater areas, hyperspectral imaging (HSI) has found widespread application in the field of object classification. The HSI is typically used to accurately determine an object's physical characteristics as well as to locate related objects with appropriate spectral fingerprints. As a result, the HSI has been extensively applied to object identification in several fields, including surveillance, agricultural monitoring, environmental research, and precision agriculture. However, because of their enormous size, objects require a lot of time to classify; for this reason, both spectral and spatial feature fusion have been completed. The existing classification strategy leads to increased misclassification, and the feature fusion method is unable to preserve semantic object inherent features; This study addresses the research difficulties by introducing a hybrid spectral-spatial fusion (HSSF) technique to minimize feature size while maintaining object intrinsic qualities; Lastly, a soft-margins kernel is proposed for multi-layer deep support vector machine (MLDSVM) to reduce misclassification. The standard Indian pines dataset is used for the experiment, and the outcome demonstrates that the HSSF-MLDSVM model performs substantially better in terms of accuracy and Kappa coefficient.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Some researchers have proposed the topic of MPR selection in improving quality of service (QoS).
The MPR selection in reducing the number of topology control (TC) packet using the two algorithms based
on three hops and the concept of OLSR-New Degree-MPR [15]. The results research show that both
proposed algorithms can reduce TC, energy consumption and the increase packet delivery ratio (PDR)
compared to the standard OLSR. However, the change in the number of nodes has not evaluated.
The selecting MPR on OLSR uses the necessity first algorithm (NFA). The simulation results using
OPNET show that the proposed algorithm can reduce TC and MPR amount by 0.7% to 11.2% compared with
greedy algorithm [16]. However, parameters such as PDR, throughput, delay, and energy consumption have
not evaluated.
Reducing and stabilizing the MPR on the OLSR by proposing two strategies, namely maximize
MPR elections globally and maintain the MPR [17]. The result of the simulation using OMNETshows that
both the proposed method can improve the performance of OLSR significantly. However, parameters such as
PDR, throughput, delay, and energy consumption have not evaluated.
The MPR selection on OLSR based on a local database of neighboring nodes extended into three
hops [18]. The MPR selection aims to reduce TC packet overhead by marking its neighbor subset as MPR.
Simulation results using the NS2 indicate that OLSR variants are better than standard OLSR based regarding
the number of TC packets, cost, and routing efficiency.
The selection of additional MPR nodes based on strong broadcasts on wireless ad hoc networks.
The proposed method selects the other MPR node so that it can include two hop MPR nodes [19]. The
number of additional MPR nodes was analyzed using mathematical modeling and simulation. Simulation
results show that the proposed method can improve throughput and delivery ratio compared to standard
OLSR. However, dynamic environmental conditions have not evaluated.
The selection of multipoint relay kinetic (KMPR) in OLSR based on mobility prediction [20].
Simulation results using NS2 indicate that the proposed KMPR method can reduce routing overhead (RO)
and delay compared to the standard OLSR. However, parameters such as packet delivery ratio, throughput,
and energy consumption have not evaluated.
MPR selection using the concept an enhanced MPR (EMPR) in OLSR wireless ad hoc
networks [21]. EMPR take into consideration the cost value as an additional factor in MPR elections.
The proposed EMPR concept producing a more extensive cover range for the MPR set compared to that
provided by MPR-based OLSR heuristics. The simulation results using OPNET show that EMPR can
decrease packet loss value based on speed changes. However, the development of parameters such as PDR,
throughput, delay, and energy efficiency has not evaluated.
MPR selection on OLSR in MANET environment based on lifetime [22]. The consideration of the
energy factor in selecting MPR makes the lifetime of the node becomes to better. Simulation result using
network simulator version 3 (NS-3) show that the MPR selection based on lifetime can increase PDF and
decrease packet loss in every addition of times. However, the change in the number of nodes has not
evaluated.
The development of algorithms in improving the Multipoint Relay selection process (MPR) based
on mobility rate (MR) [23]. MR concept proposed to reduce mobility in MANET. Simulation results using
NS3 show that the proposed mobility concept can improve network performance such as throughput, a packet
received, packet loss, packet delivery ratio, and packet forwarding. However, the parameters such as delay
and energy consumption have not evaluated.
The improved OLSR performance through new MPR elections using PSO. This article proposes
particle swarm optimization of sigmoid increasing inertia weight (PSOSIIW) to improve OLSR performance
in the reduce message load during flooding process [24]. Simulation results using NS2 show that OLSR-
PSOSIIW performance is better than OLSR standard and OLSR-PSO, particularly of delay and throughput.
However, parameters such as PDR and energy consumption have not evaluated.
MPR selection based on residual energy called energy efficient optimized link state routing
(EOLSR) [25]. The EOLSR method is an OLSR variant, in which the MPR selection and path calculation
determined by the energy level and the number of neighboring nodes. The simulation results show that the
EOLSR method can reduce residual energy in every addition number of nodes. However, such parameters as
PDR, throughput, packet loss, and delay have not evaluated.

consumption by considering node density. The node density factor affects the performance of the routing
protocol in determining the route from the source node to the destination node.
Figure 1. Flowchart of research methodology
2.1. Design of simulation
The simulation model design used consisted of the simulation program, number of nodes, packet
size, simulation area, simulation time, simulation speed, mobility model, and propagation model.
The MANET model selection used consisted of a node movement scenario with a two-ray ground
propagation model and random waypoint mobility model. The choice of two-ray ground model based on the
conditions for direct path propagation and surface reflection (ground reflection) between the sender and
receiver [26, 27]. The two-ray ground model is very accurate in estimating signal strength in large area
scales. The selection of random waypoint mobility model based on moving nodes with direction and speed
randomly to reach the destination node [28]. The area of simulation used is 1000 meters x 1000 meters with
the random waypoint model.
2.2. MANET simulation with NS-2
The research method used is simulation-based research using network simulator version 2.35
(NS2) [29] and listing program in the form of AWK script [30]. NS2 is a simulator based an open-source,
object-oriented written in C ++, and has an OTcl (Object Oriented Tool command language) as its
frontend [31]. The purpose of simulation testing is to improve the performance of OLSR routing protocol in
the selecting MPR based on the range of the most significant signal. The simulated routing protocols are
standard OLSR and OLSR uses min-max. Both routing protocols gave the same treatment with the number of
nodes varying from 25 to 200 and distributed randomly. The simulation area is 1000 x1000 meters with a
fixed speed of 20 m/sec and duration for 300 seconds. The purpose of giving a different number of nodes in
both protocols is to determine the resulting QoS performance effect. The change number of nodes affect the
performance of the routing protocol in determining the route from the source node to the destination node or
neighboring nodes. The routing protocol simulation using NS2 file type (* .tr) and the simulation results
visualized in the file (* .nam).

The OLSR standard simulation analysis and OLSR using min-max are performed based on QoS
parameters such as PDR, throughput, packet loss, delay, topology control, and energy consumption by
considering node density. The simulation result using NS2 gives a conclusion about the performance of
standard OLSR and OLSR uses min-max. The simulation parameters can see in Table 1.

3. RESULTS AND ANALYSIS
3.1. Packet Delivery Ratio (PDR)
PDR is the ratio between the numbers of packets received by the destination node by the packet sent
by the source node [32]. Figure 2 shows the PDR of the standard OLSR and OLSR uses min-max on the
number of different nodes. The performance of OLSR uses min-max more steady and increases on denser
nodes, especially at nodes 75 and 200. The increased PDR caused by the ability of min-max algorithms that
selectively select MPR nodes. Selection of particular MPR nodes causes some packets to successfully
received by the destination node. The performance of standard OLSR tends to the decrease on denser nodes,
especially at nodes 200. The reduction in packet loss on standard OLSR caused by the mobility levels
between nodes one with other nodes becomes increased in the number of denser nodes. This effect of
increased mobility causes some packets to fail to be received by the destination node. The simulation results
show that the average value of the PDR for OLSR using the min-max better than the standard OLSR.
The average of PDR for OLSR uses the min-max algorithm of 76.46% and standard OLSR of 39.99%.

3.2. Packet loss
Packet Loss is a percentage of the packets loss in connection with packets sent between the source
node to the destination node. Figure 3 shows the packet loss of the OLSR standard and OLSR uses min-max
on the number of different nodes. Performance of OLSR uses min-max is likely to be unstable and decreases
in denser nodes, especially at nodes 75 and 200. The decreasing in packet loss caused by the missing packet
from the source node to the destination very few. The performance of standard OLSR tends to be unstable,

and the resulting packet loss value increases in the denser nodes, especially at nodes 200. The increased
packet loss on standard OLSR occurs due to the number of missing packets in the destination node. The
average of packet loss for OLSR uses min-max of 23.54% and standard OLSR of 60.03%.
Figure 4. Simulation result of packet loss
3.3. Throughput
Throughput is the rate of effective data transfer calculated in bytes per second (Bps) as the total
number of packets received successfully in units of time [33]. The performance of the routing protocol
become better if the resulting throughput increased. Figure 4 shows the throughput of OLSR and OLSR
standard using the min-max on the number of different nodes. The throughput performance of OLSR uses the
min-max tends to be stable on denser nodes, especially at nodes 150 and 200. The throughput performance of
the standard OLSR tends to be unstable and decreases in the denser nodes, especially at node 200. However,
the original OLSR performance better than OLSR using the min-max particularly in each node addition.
The increased throughput of standard OLSR caused by routing table update to all nodes, although nodes in
the condition do not transmit data. Update of the routing table in each node shorten in finding the route.
The average throughput value generated by OLSR uses min-max of 353.33 Kbps and standard OLSR of
417.38 Kbps.
Figure 4. Simulation result of throughput
3.4. Delay
Delay is the average time required to send packets from the source node until successfully received
by the destination node [34]. Figure 5 shows the delay of standard OLSR and OLSR using the min-max on
the number of different nodes. Delay in standard OLSR tends to increase on each additional node. The delay
in OLSR using the min-max tends to decrease in the more dense nodes. However, the delay on the standard
OLSR better than OLSR uses min-max in finding the route. The decreases of delay because standard OLSR
always updates routing tables that have compiled before data packets sent. The OLSR uses min-max to find

422
the route long enough because the selection of routing table updates collected based on signal coverage.
Signal coverage on the number of denser nodes needs a long time to find the route. The average delay for
standard OLSR of 15.42 milliseconds and OLSR uses min-max of 24.76 milliseconds.
Figure 5. Simulation result of the delay
3.5. Topology Control (TC)
TC is the total number of routing packets transmitted during the simulation. The Packets that sent
over multiple hops counted as one transmission (one jump). Figure 6 shows the TC on standard OLSR and
OLSR using the min-max based on the number of different nodes. Movement of TC on OLSR uses the min-
max at nodes 25 to 100 tends to increase. However, the number of denser nodes TC values tend to decrease,
especially at nodes 150 and 200. The reductions of TC in OLSR using min-max occurs because of the
absence of excessive data transmission. Movement of TC on standard OLSR tends to increases every
addition number of nodes. The average value of TC on OLSR using the min-max of 1171.67 packets and
standard OLSR of 1266.17 packets. This decreases of TC indicate that OLSR using min-max provides a
small data redundancy effect compared to standard OLSR.
Figure 6. Simulation result of topology control
3.6. Energy consumption
Energy consumption is the number of energy required by a node to transmit and receive packets.
Figure 7 shows the performance of energy consumption in the standard OLSR and OLSR uses min-max
based on the number of different nodes. The performances of standard OLSR and OLSR using min-max
regarding energy consumption tends to be unstable and decreases in the denser nodes, especially at nodes 100
to 200. However, standard OLSR consumes more energy than OLSR uses min-max. The decrease in
overhead in the determination of the route on OLSR using the min-max causes resulting energy consumption

lesser than the standard OLSR. The average energy consumption value of OLSR using min-max of 14.08
milliwatts and standard OLSR of 16.4542 milliwatts.
Figure 7. Simulation result of energy consumption
4. CONCLUSION
This study proposes a min-max algorithm to improve OLSR. The performance of standard OLSR
and OLSR using the min-max analyzed based on service quality (QoS) parameters such as PDR, packet loss,
throughput, delay, and energy consumption with considering node density. The simulation results show that
OLSR using min-max can increase PDR, packet loss and decrease TC, energy consumption compared to
standard OLSR. The throughput and delay generated by the OLSR standard are better than OLSR using min-
max. However, increased throughput and delay in OLSR using min-max tends to be stable and increase on
denser nodes. Increased PDR, packet loss, and TC decrease, energy consumption shows that OLSR
performance using min-max is highly selective in selecting MPR nodes.
