Implementation of Enhanced & Adaptive Intrusion Detection System for MANET

Abstract

Mobile Ad hoc network has become one of the most important wireless communication mechanisms. Mobile Ad-hoc Networks (MANETS) is a collection of wireless mobile nodes without any infrastructure support, in which every single node works as both transmitter and receiver .Nodes in MANET can communicates directly with each other when they are in a same communication range. The self-configuring ability of mobile nodes in a MANET made them popular in vital mission applications like military use or emergency recovery. However the open medium of MANET allows them vulnerable to attacks. Because of MANET’s distributed architecture and changing topology a traditional centralized monitoring system is not longer feasible in MANET .In this case intrusion detection should be focused as another part before an attacker can damage the structure of the system. So, this work presents various intrusion detection system named as TWOACK, AACK, ACK and Enhanced Adaptive Acknowledgement (EAACK).Enhanced intrusion detection system use digital signature technique to digitally signed packets before they are transmitted to ensure integrity and confidentiality of packets.
