Xiao Fu · Chuangan jishu xuebao · 2010
In wireless sensor networks,the coverage of the target area and the network energy consumption are important indicators of its performance.Through rational configuration of nodes,the network coverage can be guaranteed and the energy consumption can be balanced.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.The simulation result shows that the strategy can effectively reduce the overlapped sensing regions and blind regions comparing to traditional energy-saving coverage strategies.Therefore,the network coverage quality is improved and energy consumption reduced.
