Ad-hoc networks, due to their improvised nature, are frequently established insecure environments, which makes them susceptible to attacks. These attacks are launched by participating malicious nodes against different network services. Routing protocols, which act as the binding force in these networks, are a common target of these nodes. Ad hoc On-demand Distance Vector routing (AODV) is a widely adopted network routing protocol for Mobile Ad hoc NETwork (MANET). Black hole attack is one of the severe security threats in ad-hoc networks which can be easily employed by exploiting vulnerability of on-demand routing protocols such as AODV. In this paper, the authors proposed a solution for identifying the malicious node in AODV protocol suffering from black hole attack.
