Abstract

Objectives: To implement misdirection attack and analyze network performance of LEACH protocol; to propose node localization based technique to detect and isolate misdirection attack; to implement existing and the proposed techniques and compare the consequences in terms of throughput, delay and energy consumption. Method: In this manner, a novel procedure has been proposed for the detection and isolation of the misdirection assault in Wireless Sensor Networks. The proposed technique is based on node localization, in which delay per hop is counted and the node which is increasing delay maximum times which can be detected as a malicious node. Findings: The simulation of the planned algorithm is performed in NS2 by taking area of 800*800 meters and the numbers of nodes are 20. It has been analyzed that network throughput is to raise and the delay and energy utilization of the sensor nodes lessened.
