Abstract
Objective: Mobile Adhoc Networks contains set of mobile nodes does not have a fixed structure. It is very important to protect the network secure. The main aim of the paper is to protect the network from worm hole attack using path tracing algorithm with the advancement of aodv and compare the performance parameters. Methods: We propose path tracing algorithm for detection of worm hole attack as a extension of aodv protocols the path of the node effectively computes the per hop distance of its neighbor node with per hop distance of the previous node to identify the worm hole attack. NS2 simulator is used to compare the performance parameters of the worm hole attack. Conclusions: Simulated parameters like packet delivery ratio, delay, and packet loss with attacker and without attacker are done and the detection ratio is identified.
