Abstract: From past few years, wireless networks are mostly preferred because of its mobility and scalability characteristics. Mobile Ad hoc network (MANET) is one of such wireless communication mechanisms. A MANET is an infrastructure-less network consisting of self-configuring mobile nodes connected by wireless link. The nodes communicate with each other directly or indirectly with the help of neighbours to store and forward packets. The open medium and wide distribution of nodes makes MANET vulnerable to malicious attacks. To address the security, it is essential to develop an Intrusion Detection System (IDS) specially designed for MANET which can detect malicious attacks before they do any significant damage to the network. For this concern a secure intrusion detection system, EAACK is developed which solves the limitations of earlier systems. The proposed system evaluates EAACK with AODV routing protocol thereby providing better performance for large size MANET.
