Mobile Ad-hoc NETwork (MANET) is the network which forms when needed with no existing or fixed infrastructure. It is an autonomous system of mobile hosts connected by wireless links. The mobile hosts are free to move independently in any direction. Due to the infrastructure-less design and self-organized mobile nodes the MANETs are prune to different problem, such as routing attacks, security breach problem; one among them is malicious node attack. The malicious node attack is an active attack which causes severe damage to the network.
