Most of the researches focus on the secure and reliable communications in Mobile Ad hoc NETworks (MANETs) because of the presences of malicious nodes, unreliable wireless media, host mobility and lack of infrastructure. However the basic idea of forming an Ad Hoc network is utilizing the cooperation between nodes which becomes critical to maintain QOS. Nodes which are non-cooperative are called as selfish nodes. Not much work has been done to find the effect of selfish nodes in a MANET. In this paper, it is proposed to evaluate the performance of a network under the impact of selfish nodes.
