The conveyed idea of a MANET endeavors to give repetition by enabling different routes to be shaped, when a route fails because of battery depletion or noxious assault options are promptly accessible. Black hole or Gray hole assault ruins this repetition by detaching the private channel can disengage a dominant part of dynamic courses. These assaults are troublesome in MANET, when it is executed by changing the working of steering conventions like AODV in which routes are chosen based on

The paper proposes a way to deal with adjust the working of AODV keeping in mind the end goal to execute and identify gray hole and black hole nodes in network. AODV routing protocol is utilized as a part of multi hop ad-hoc systems. The AODV convention does not require any sort of system foundation or focal organization. This examination work is altering the working of existing AODV convention as WRP (AODV with wormhole) for usage and discovery of individual black hole, cooperate black hole, gray hole assaults. It finds the faulty nodes in the way based on delay and forwarding ratio.
