A Fuzzy Approach to Avoid Selective Forwarding Attacks and Energy Efficient Path Selection in Wireless Mesh Networks

Wireless Mesh Networks (WMNs) have emerged as a key technology which provide support for next generation wireless networking and provide services that are not assisted by other Wireless Network. WMNs are deployed in an adverse environment. Due to which various types of security attacks can occur in WMNs such as wormhole, acknowledgement spoofing, black hole attack, sybil etc. So security plays an important role in WMNs. In this paper we study selective forwarding attack, how it affect the performance of WMNs and provide a Fuzzy based algorithm to protect WMNs against selective forwarding attack and provide a energy efficient path from transmitter to receiver. The performance is evaluated in terms of throughput, packet delivery ratio and average end to end delay. Simulation results have been provided to illustrate the efficiency of the proposed algorithm.
