A Mobile Ad-hoc NETwork (MANET) is a collection of mobile nodes and is autonomous having communication through the insecure wireless links. Security is very important issue for this type of networks because the nodes in the network dynamically add and join the network. This nature of nodes makes them vulnerable to malicious attacks. One of the widely adopted network routing protocols for Mobile Ad-hoc NETwork (MANET) is AODV (Ad hoc on demand Distance Vector) protocol. Black hole attack is one such attack in which a malicious node makes use of susceptibility of Route REQuest (RREQ) packets of routing protocol to advertise itself with a fake Route REPly (RREP) message as having the shortest path to the destination node.
