Mobile ad hoc networks are composed of mobile nodes connected by wireless links without any pre-existing infrastructure. MANET nodes rely on network cooperation schemes to properly work, forwarding traffic unrelated to its own use. However, in the real world, most nodes may have a selfish behavior, being unwilling to forward packets for others in order to save resources. The selfish nodes are not malicious but are reluctant to spend their resources such as CPU time, memory and battery power for others. Therefore, detecting these nodes is essential for network performance.
