Abstract: The energy consumption is a primary consideration factor in the Wireless Sensor Networks (WSN). To balance the energy consumption of each node and enhance the lifetime of the network, in this paper, a fuzzy logic approach to cluster-head election which is called FLCHE is proposed. This algorithm fully considers the residual energy of the node, the energy consumption rate, and the distribution density of the node. Simulation with Matlab shows, compared to the LEACH, FLCHE balance the energy consumption of the nodes more and prolong the network lifetime. The overall performance is better than LEACH.

 

Keywords: Wireless sensor networks, energy consumption balancing, LEACH, FLCHE.
