Enhanced TESRP Protocol for Isolation of Selective Forwarding Attack in WSN

Abstract

A wireless sensor network is the combination of large numbers of nodes connected to each other in order to communicate with other networks over a particular territory. Within the sensor networks there are two types of attacks which are active and passive attacks. The selective forwarding is the active type of attack in which malicious nodes drop some packets in the network which affect network performance which is considered in this paper. In this research work, technique of threshold is designed which detect and isolate malicious nodes from the network. The simulation results shows improvement in terms of dead nodes, throughput and packet loss.
