Homogeneous and hetrogeneous intrusion detection system in mobile ad hoc networks

Nowadays, Mobile Ad-hoc networks (MANET) are more vulnerable to various types of attacks due to insecure communication medium and infrastructure less environment. In this paper a system is proposed to detect the misbehaving node in a homogeneous as well as a heterogeneous environment. In such networks, to monitor the behavior of nodes over a wide environment it is proposed to realize an intrusion detection system with only a single monitor nodeto be elected. This node will monitor the functions of each node in the entire network. If there is any disruption in the normal behavior of a communication channel then the monitor node will identify the node, which is a malicious node.
