Malicious Node Detection in MANET

Sujitha.R, Dr.Thilagavathy.D

Mobile Ad hoc Network (MANET) is an infrastructure less network. It does not require any fixed network. Each and every node is act as a transmitter and a receiver. All the nodes in the MANET are assumed as working within a cooperative and friendly network context. There is no base station to control the moving devices. So there is no security to protect the nodes. Any node can act as a misbehaving node. Such uncooperative behavior can greatly degrade network performance and may even result in total communication breakdown. So the malicious nodes can easily attack the mobile nodes. In this paper, we have proposed an Intrusion Detection System in which the malicious nodes are detected and there by the performance of the network will be increased.
