A Mobile Ad hoc NETwork (MANET) is an independent system of mobile routers attached by wireless links. In MANETs protecting a network from malicious attacks is an important and challenging issue. In this paper, a new mechanism has been proposed to detect and defend the network against such attack from the malicious nodes. The proposed algorithm has been incorporated on AODV routing protocol. The proposed algorithm not only works against the black hole but also against nodes which are showing less misbehavior in them. It is protecting the network by detecting and deactivating the malicious activities of node.
