PERFORMANCE ANALYSIS OF ADHOC ON DEMAND DISTANCE VECTOR PROTOCOL WITH BLACKHOLE ATTACK IN WSN

Abstract

The security is major challenging issue in wireless sensor network applications because they are operated in public and unrestrained areas which also makes difficult to protect against tampering or captured by an adversary force that can launch insider attacks to make a node compromised. One type of such attack is black hole attack. Existing AODV routing protocol does not have mechanism to defend against such attacks. In this study, we comprehensively investigates the performance of AODV protocol by simulating it on the various network parameters with various number of blackhole nodes. The metrics for evaluation has been considered as packet delivery ratio, end to end delay, normalized routing overhead and total number of packets drop. The simulation results show that blackhole attack severely degrades the performance of WSN.
