Executive Summary

A mobile ad hoc network is a collection of mobile nodes that are interconnected via a wireless medium forwards packet to other nodes through multi hop mechanism. The genuine intermediaries relay the packets intended for the indirect radio range destination node. The cooperation existing between the intermediate nodes acts as a strong determinant for successful routing in ad hoc network. The association between these nodes can be weakened by the advent of wormhole adversary inside the network. This adversary tries to deteriorate the routing fabric embedded in this network by short circuiting the normal flow of packets through a resource enriched out of band channel exclusively dedicated for this purpose.
