"In this paper, the authors cover a novel approach for detecting selfish nodes in MANET. Mobile Ad hoc NETworks (MANETs) are composed of many mobile devices with wireless interface. The network operates well without any infrastructure. The source node can relay packets to the destination node through other nodes in MANET. The misbehavior of selfish nodes such as, do not participate in routing process, intentionally delay the RREQ packet, dropping of data packet, do not reply or send hello messages."
