Mobile ad hoc networks typically work in an open un-trusted environment with little physical security, and are vulnerable for different type of security attacks. one attack in ad hoc networks is the wormhole attack that has received a great deal of recent attention. In wormhole attack, an attacker captures the packets from one point in the network and tunnels them to a distant location where they are replayed, typically without modification. Thus the detection of wormhole is a very important in the network.
