An Improved Intrusion Detection Technique for Mobile Adhoc Networks

Abstract

In this paper, we propose a Distributed Intrusion Detection System to protect Mobile Adhoc Networks from intruder-induced attacks. The highly dynamic, decentralized nature of these networks and a lack of infrastructure means that these networks are exposed to various kinds of security threats like spoofing, DOS attacks etc. We propose a new procedure to circumvent the intruder node and a technique to detect the intruder node in a co-operative manner based on the history of the failed paths due to intrusion. The experimental setup and the obtained results are presented discussing the various performance and security issues in the proposed protocol.
