Fuzzy Based Dynamic Load Management Policy for Wireless Sensor Networks

Energy efficient routing is the major goal to design an effective and high performance wireless sensor network (WSN). To design energy efficient routing technique, it is essential to consider load balancing as unavoidable phenomena. In this paper, we present a new dynamic load balanced routing policy offering a high level of energy efficiency. Unlike existing routing solutions, our scheme is based on a distributed and load balancing scheme. Furthermore, it employs a new fuzzy based node classification scheme to enhance the network life span and coverage of the network. Node decides multi-hop data transmission path according to node efficiency. Therefore, proposed policy distributes routing load throughout the network. Extensive analysis and simulation show that our approach improves many important performance metrics such as: network life span, global energy loss, transmission delay, and packets delivery ratio.
