Wireless networks are gaining popularity to its peak nowadays, the desire to be connected anytime and anywhere has led to the development of wireless network, opening new vista of research in pervasive and ubiquitous computing. Mobile Ad hoc NETwork (MANET) has distributed mobile wireless nodes, which do not have pre-determine topology and pre-existing infrastructure mobile nodes that can arbitrarily change their geographic locations and random mobility with constrained resources, ad hoc networks are vulnerable due to their structure less property. During the wormhole attack, a malicious node captures packets from one location in the network, and "Tunnels" them to another malicious node at a distant point, which replays them locally.
