A Performance Study of Various Security Attacks on AODV Routing Protocol in MANET

Mobile Ad-hoc Network (MANET) is a self-configuring wireless network of movable and independent nodes which operate without the support of any permanent infrastructure, hence MANET has dynamic topology. In MANET, each node forwards traffic unrelated to its own use. Despite the proliferation of MANET, it is prone to various attacks which include blackhole attack, grayhole attack, flooding attack, wormhole attack etc. This paper presents the analysis of the effect of various security attacks on the performance of AODV routing protocol against various parameters such as throughput, packet delivery ratio, packet loss, and mean-hop, normalized routing overhead and end-to-end delay
