In mobile ad hoc networks, data transmission is performed within an untrusted wireless environment. A wireless networks are more vulnerable to different types of attack than wired network. Various kinds of attack have been identified and corresponding has been proposed. Wormhole attack is one of the serious are attacks which forms a serious threat in the networks, especially get against many ad hoc wireless routing protocols and location-based wireless security system. In which traffic is forwarded and replayed from one location to another through the wormhole tunnel without compromising any cryptographic techniques over the network.
