A mobile ad hoc network (MANET) is an autonomous network that consists of mobile nodes that communicate with each other over wireless links. In the absence of a fixed infrastructure, nodes have to cooperate in order to provide the necessary network functionality. One of the principal routing protocols used in Ad hoc networks is AODV (Ad hoc on demand Distance Vector) protocol. The security of the AODV protocol is threaded by a particular type of attack called `Black Hole' attack. In this attack a malicious node advertises itself as having the shortest path to the destination node. To combat with black hole attack, it is proposed to wait and check the replies from all the neighboring nodes to find a safe route but this approach suffers from high delay. In this paper, an approach is proposed to combat the Black hole attack by using negotiation with neighbors who claim to have a route to destination. the Simulation's results show that the proposed protocol provides better security and also better performance in terms of packet delivery than the conventional AODV in the presence of Black holes with minimal additional delay and Overhead.
