Abstract
Now a days, selfish nodes is a huge problem in WSNs. In Wireless Sensor Network (WSN) communication, every node forwards the data packets to neighboring nodes and use up its battery power, bandwidth and memory space. All the nodes transmits packets to other nodes according to their necessities in the ideal situation. Presence of selfish node in the network creates data communication failure and nodes don't transmits packets and utilize the network resources for its own profit but it refuses to share their personal resources for other nodes. Due to presence of selfish node in the network, the network is defective and the data communication between nodes is disrupted. It is an important issue to timely detect a selfish node and its behavior in wireless sensor networks. In this paper we have proposed an algorithm for detection of a selfish node in a given network topology.
