A Mobile Ad-hoc NETwork (MANET) is a self-configuring infrastructureless network of mobile devices connected by wireless links. As there is no fixed infrastructure in MANET, mobile nodes need to communicate with each other by exchanging control and data packets to provide assured functionality to the network. For making communication possible in MANET, different routing protocols are used. Ad-hoc On demand Distance Vector (AODV) protocol is the principle routing protocol used in MANET. The AODV protocol is threaded by a security problem called cooperative black hole attack, in which all malicious nodes introduces themselves as having shortest path to the destination node.
