This paper presents a coverage optimization strategy for energy balance in wireless sensor networks, in which the sensing distance of nodes is adjustable. The strategy achieves coverage energy optimization balance with a prerequisite of an acceptable coverage quality of network area. Using particle swarm algorithm, it firstly optimizes the layout of the nodes in the network, based on which it then adjusts the sensing distance of the nodes to achieve best energy consumption performance of the network coverage.
