Ad-hoc networks don't have need of any preset infrastructure such as base stations or mobile switching centers. A mobile ad-hoc network until the end of time suffers by the trouble of some attacks as the network is globally unlocked and these attacks may create some selfish nodes. A selfish node is one that tries to utilize the network resources for its own profit but is reluctant to spend its own for others. If such behavior prevails among large number of the nodes in the network, it may eventually lead to disruption of network. The paper is on the subject of detection of selfish node attack between the communication taken place between the source and the destination.
