Abstract
Mobile Adhoc Network (MANET) is infrastructure less as it does not require any specialized router to do the routing tasks. Instead, each and every node in MANET acts as a router as well to perform the routing tasks with the dependability on a routing protocol. This feature of MANET leads to serious security threats affecting the performance of the network. The attacks may be done at various layers of the network. Thus, security becomes the vital service for the success of MANET. Network Layer protocols extend connectivity from neighboring 1-hop nodes to all other nodes in MANET. A variety of attacks targeting the network layer have been identified. One such critical problem is wormhole attack. This paper proposes a reputation based isolation of wormhole node, which provides a trust computation to the Worm Hole Avoidance protocol (WARP), leaving the normal node without any support for additional hardware . It combines the advantages of WARP and the basic trust model.
