This paper presents an intrusion detection mechanism that uses collaborative efforts of the nodes in a neighborhood to detect aberrant behavior in a mobile ad hoc network. A node showing this kind of behavior is termed as a malicious node. 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. This technique uses message passing between the nodes. A node called the monitor node initiates the detection process. The monitor node sends data packets to two other nodes, called target nodes, through the node which has to be tested for malicious behavior.
