A mobile ad-hoc network is a self-configured collection of mobile nodes in which there is no need of predefined infrastructure. In this network nodes can arbitrarily change their geographic locations. MANET is more vulnerable to cyber attacks than wired networks because of no any central coordination mechanism. The black hole attack at network layer is the most attention seeking attack in AODV routing protocol as compared to other protocols. This paper presents a review of Black hole attack in AODV routing protocol.
