Performance evaluation of AODV routing protocol under Black Hole attack with varying Black hole nodes

A Mobile ad-hoc network (MANET) is a temporary network set up by wireless mobile computers (or nodes) moving arbitrary in the places that have no network infrastructure. Due to this it is vulnerable to various kinds of security threats. Black hole attack is one of such threats. This paper lead emphasis on AODV routing protocol in MANET, along with various types of security attacks and security threats with major concern on the Black Hole attack.
