The Mobile Ad hoc NETworks (MANETs) is a collection of wireless nodes which interact with each other by sending packets to one another or on behalf of another node, without any central network infrastructure to control data routing. For communication, the nodes cooperatively forward data packets to other nodes in network by using the routing protocol. But, these routing protocols are not secure, thus paving the way for the MANET to be open to malicious attacks. A malicious attack which is commonly observed in MANET environment is wormhole attack.
