Mobile Ad Hoc NETwork (MANET) system is not only subject to most of the well known attacks and threats that the wired and conventional wireless network suffered, but also a large number of additional attacks and threats. Security has become a primary concern in order to provide protected communication between mobile nodes in a hostile environment. Security is not a single layer issue but a multi-layered issue. An individual mobile node may attempt to benefit from other nodes, but refuse to share its own resources. Such nodes are called selfish or misbehaving nodes and their behavior is termed selfishness or misbehavior.
