A survey on black hole attack in mobile ad hoc networks

A MANET consists of a group of wireless mobile nodes. These nodes are arbitrarily moving and communicating one another over wireless links. Due to some unique characteristics such as open medium, changing network topology, distributed cooperation, limited battery power, and limited bandwidth information exchange in the MANET becomes challenging job. In infrastructure less network node needs to cooperate to each other to provide necessary network functionality. AODV routing protocol is most preferably used in MANET. An information exchange is an important task in the security of whole network. In this article we study the routing security problems of MANET and examine “Black hole attack” which can easily be employed against the MANET in detail.
