FFMS: Fuzzy Based Fault Management Scheme in Wireless Sensor Networks

Fault detection and fault management in wireless sensor network is a major challenge in its performance analysis. In this paper we propose a fuzzy logic based fault detection and fault management scheme (FFMS). Fuzzy rules are proposed for efficient detection of different types of nodes named as normal node, traffic node, end node, and dead node. Fuzzy interface engine categorizes the different nodes according to the chosen membership function and the defuzzifier generates a non-fuzzy control to retrieve the various types of nodes. Next, active nodes’ performance analyses are done using five traditional metrics. Experimental results manifest that the proposed FFMS scheme is more effective for fault management in WSN.
