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, the authors focus on developing effective detection approaches. In this paper, they 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.
