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 d...

Energy conservation plays a crucial in wireless sensor networks since such networks are designed to be placed in hostile and non-accessible areas. While battery-driven sensors will run out of battery sooner or later, the use of renewable energy sources such as solar power or gravitation may extend the lifetime of a sensor. We propose to utilize solar power in wireless sensor networks and extend...

The routing protocol of WSN based on clustering hierarchy has been one of the important research topics. An improved strategy based on LEACH (Low Energy Adaptive Clustering Hierarchy) is proposed in this paper, which uses the PSO algorithm to optimize clustering process by considering the energy, the communication costs, the load balance and other factors to determine the cluster-head node. The...
