A Mobile Ad hoc NETwork (MANET) contains a collection of wireless mobile nodes that forms a temporary network without having any fixed infrastructure or centralized administration. MANET is assailable to routing misbehavior. The authors are worried of an especially severe security attack that affects the MANET routing protocols, it is called the wormhole attack. During the attack an attacker captures packets from one location in the network, and tunnels them to other attacker at a distant point, which replays them locally.
