Abstract: Due to wireless communication in Mobile Ad hoc Network (MANET) it is vulnerable to different routing attacks. One of the severe network layer attacks is wormhole attack, which totally disrupts the channel without disturbing the traditional routing protocol. In this paper, we have discussed about wormhole attack, its behavior and technique of its deployment, detection and prevention available currently. At last we suggested a cluster-based energy-efficient method to detect and prevent malicious node in the cluster.
Keywords: MANET, AODV, WSN, Wormhole, Cluster-based.
