MANET is a less infrastructure network with vigorously changing topologies and arbitrary communicating node. At this time the mobile nodes communicate directly with additional nodes without any router and hence the preferred functionalities are embedded to each node. Since the MANET consist of mobile nodes with fewer configurations of hardware and requirements compared to a router, hence protocols and routing used are of lightweight functionalities. The range of protocol in MANET is categorized in two types: proactive and reactive. This paper deals with enhancing MANET security through intrusion detection system for the AODV reactive protocol.
