An Ad-hoc network is a group of wireless mobile nodes that shapes a temporary network without any infrastructure and centralized management. Each mobile node functions not only as base station but also as router forwarding packets for other mobile nodes in the network. One of the dangerous attacks in an Ad-hoc network is named wormhole attack which two or more destructive nodes record the packets at one point, and transmits them by a wired or wireless to another point in the network. Wormhole attack is so strong and detection of this attack is hard. Also, the wormhole attack may cause another type of attacks like Sinkhole or Select forwarding.
