Executive Summary

A Mobile Ad hoc NETwork (MANET) is more vulnerable to routing attacks due to its open nature of medium, decentralized administration, lack of security, dynamic network topology, multi-hop routing, energy limited operation, lack of scalability etc. There are high probabilities for misbehaving node to launch any kind of attack in MANETs. The misbehaving nodes are of two kinds namely selfish and malicious. Selfish nodes use the network resources only for their own purposes and do not participate or cooperate in the routing process. Unlike selfish nodes, malicious nodes do not conserve battery life but they indulge in wasting network resources. Due to their greater vulnerability, MANET should consider the security system as a mandatory to protect its user from routing attacks despite of the application environment
