The wireless nature of communication makes wireless networks unreliable as any attack with intent to steal the data can do so by deploying malicious nodes in the network. In MANET different mobiles are connected through wireless link. There are different types of attacks possible in MANET. Wormhole attack is one of the types. In this type of attack node transfer from other path rather than path assigned to source and destination. So lost of data is possible. In this research work, the novel scheme is proposed which detect and isolation malicious nodes from the network. The malicious nodes are responsible to trigger wormhole attack in the network. The proposed technique is implemented in NS2 and simulation results shows that proposed technique performs well as compared to other techniques.
