In Mobile Ad hoc NETworks (MANET), various types of Denial of Service Attacks (DoS) are possible because of the inherent limitations of its routing protocols. MANET rely on cooperation of all participating nodes, thus they are vulnerable to selfish nodes. 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. These selfish nodes may severely affect the performance of network. Selfish node attack is a kind of Passive attack. In this paper misbehavior of Selfish Nodes is evaluated by finding the packet delivery ratio, energy consumption, end to end delivery and collisions by varying node mobility and number of attackers.
