A wireless ad-hoc network is a temporary network set up by wireless mobile nodes moving arbitrary in the place that has no network infrastructure. Basically wireless or mobile networks are evolved to replace the wired networks from traditional scenario to new paradigm. The mobile ad hoc networks are purely infrastructure less network. Due to this vulnerabilities of the network are unprotected to many attacks. In this paper, the authors are discussing about Black hole attack. In this attack a malicious node advertises itself as having the shortest path to specific node to absorb packet to itself. So to identify the possibility of occurrence of black hole attack they simulate AODV protocol with NS2 tool.
