In present scenario, ad hoc network become the prominent mode of communication for mobile devices.Hence, becoming a elementary field of research.Since ad hoc networks are infrastructure less networks and the nodes in ad hoc networks are connected by a wireless links.As nodes are connected by wireless links, its becomes easier for attacker to disrupt in the ad hoc networks.Therefore security is the major issue in ad hoc networks as compared to wired network.In this paper, we are discussing the various attacks which are possible in MANET due to fabrication and worm hole attack in AODV and how to secure AODV against wormhole attack using token based approach.The propose method reduces the packet loss due to malicious nodes to a considerable extent and hence enhance the performance.
