Wireless sensor networks are widely used in many applications like battlefield monitoring, environment monitoring, and so forth. In all of these applications the cooperation among various sensor nodes is needed to forward the data packets to the base station. However, it expends the various resources of a sensor node such as battery power, storage, and processing power. Therefore, to conserve its own resources a node may become selfish by not forwarding the data to the others. This kind of attack has serious consequences if the attacker node is the leader of a cluster. In the presence of attack the base station will not be able to get the data from the victimized cluster while resources of the member of that cluster are being consumed. In this paper we propose a scheme called window based scheme (WBS) to detect this kind of misbehavior in WSN. Our detection scheme is energy efficient because most of the computations are done at base station only. Simulation results prove that our method detects and removes the attacker effectively and efficiently.
