A modified AODV protocol to detect and prevent the wormhole usingh using hybrid technique

In Mobile Ad hoc Network (MANET), mobile node is responsible for the route establishment using a wireless link where each node behaves like both, as a host and a router. There are number of security threats in MANET possible because of its open untrusted environment with the little security arrangement. Among all of the security threat, a worm hole is considered to be a very serious security threat over MANET. In a worm hole, the two selfish nodes which are very far away to each other geographically, makes a tunnel between them to hide their actual location and try to believe that they are true neighbors and makes the conversation through the wormhole tunnel. Recently, the research will focus over wormhole detection and prevention, but an enhanced technique having lower network overhead and a lower battery power consumption in order to the longer survival of the network with fast response is needed. In this paper, the technique of dynamic wormhole detection and prevention AODVWWP has been proposed, which is based on a hybrid model that encapsulate the location, neighbor node and the hop count method.
