Efficient routing for jamming aware data transmission in wireless networks

Abstract

With recent advancements, Wireless Sensor Network (WSN) have greatly provide intention to sense various environmental distortions, security issues, data processing etc. The drastic problem in the WSN is jamming attack which is available inside the network. It may degrade the overall performance of the network and also obstruct the communication that takes place over there. However, various techniques used for effectively tracing the attack in multi-hop sensor networks and then alternate path is chosen to securely transfer the packets. The proposed work implemented Efficient Search Algorithm (ESA), Augmented Particle Swarm Optimization (APSO), Efficient route selection Routing Information Protocol (ERS-RIP) and APSO based Routing Protocol for Low-power and Lossy Networks-Secure Routing (APSORPL-SR). Each of these routing protocols and the algorithms offer a great role to improve the data transmission by considering node life time improvement and minimal energy consumption. In addition, various parameters are analyzed in the simulation setup using NS2 software. Efficient Search Algorithm is effectively used to trace the location of jammer. For the purpose of Jammer tracking, a node in the network must be chosen as observing node. The observing node is chosen in such a way that it can be able to obtain the signal of the jammer and discover the region of the jammer. ESA works are based on signal strength which is measured by observing nodes present within the network. Then this received signal strength is compared with the threshold value in order to confirm the attack. Whenever the jammer starts moving away from the observing region, the next observing node will be selected by means of handover process. The portablejammer is traced by using Received Signal Strength Indicator (RSSI) measurement from the received signal of the node. Jammer estimated path is identified in each time slot. The proposed work involves four stages to identify the portable jammer path. The following steps are i) Observing node selection ii)
