MANET (Mobile Ad - hoc network) is group of mobile nodes interconnection .MANET depends on the nodes cooperation for working properly. MANET basically assumes that nodes participate honestly in packet forwarding. But some node s may refuse to participate in the packet forwarding so that they can save their resources, leading to selfish behavior of the node. This affects the working of the network. Currently many are using watchdog for the detection of selfish nodes, but the dete ction by the watchdogs may lead to wrong result, generating false positive and false negative. Thus depending totally on watchdog may decrease the network performance. This paper proposes a method when two nodes come in contact with each other the informat ion about selfish nodes is shared. This method will decrease the time and increase accuracy of detection .
