A Mobile Ad-hoc NETwork (MANET) is a collection of mobile nodes and is autonomous having communication through the insecure wireless links. The nodes in the network dynamically add and join the network. Due to this kind of nature nodes are vulnerable to various kinds of attacks. There are many threats in wireless Mobile Ad-hoc NETworks (MANETs). MANETs suffers from intrusion in which a malicious node may or may not participate in route discovery mechanism with an intension to degrade the overall network performance.
