A Study on Wormhole Attacks in MANET

Abstract

An Ad-hoc network is a self-organized network, without a central coordinator, and which frequently changes its topology. In this paper, we have analyzed the performance of Mobile Ad-hoc Networks (MANET) under wormhole attack. Multiple QoS parameters have been considered here such as throughput, delay, packet delivery ratio, node energy and node density. The NS2 network simulator has been used and the reference point group mobility model (RPGM) is considered to study the effect of node density and the initial energy on the throughput.
