Abstract : Performance of mobile ad hoc networks (MANETs) increases by the cooperation of mobile nodes among themselves. In MANETs, mobile nodes share their resources such as battery power, memory, and bandwidth. But, in the real world some nodes do not want to contribute their resources either fully or not at all and thereby storing their resources for future use. So these nodes behave as selfish due to their resource constraint. In this work, we propose an approach for detection of the selfish nodes in MANET and avoid them during the data distribution process when there is sybil attack by considering the routing optimality, checking optimality, and forwarding optimality. The analysis of the simulation results indicate that the network performance has been increased as compared to the traditional network in terms of data accessibility and hence decreasing overall selfishness alarm after detecting the selfish nodes.
