Collaborative Anomaly-based Intrusion Detection In Mobile ad hoc Networks

Abstract

Intrusion Prevention is first line of defense against attacks in MANET. Intrusion Detection and response presents a second line of defense. New vulnerabilities will continue to invent new attack methods so new technology such as MANET, we focus on developing effective detection approaches In this paper, we present an intrusion detection system for detection of malicious node in mobile ad hoc network. The technique is designed for detection of malicious nodes in a neighborhood in which each pair of nodes are within radio range of each other. Such a neighborhood of nodes is known as a clique. [1] This technique is aimed to reduce the computation and communication costs to select a monitor node and reduces the message passing between the nodes to detect a malicious node from the cluster hence there very less traffic and less chances of a collision.
