摘要

针对节点冗余造成无线传感器网络(WSN)瓶颈节点能量消耗过快的问题,提出了一种基于节点轮换休眠的能量优化方法.首先建立了WSN能量优化的多目标数学模型,利用多目标规划问题的标量化处理将问题转化为单目标优化问题.然后提出节点轮换休眠策略算法.实验表明,本算法对WSN优化后的能量节约率在20%以上,且瓶颈节点能量消耗更加均匀.因此它能有效提高无线传感器网络的性能,是一种应用性较强的WSN能量优化算法.%Aiming at the problem that the energy of bottleneck node of Wireless Sensor Network(WSN)is Consuming too fast due to the redundant nodes,a method of the energy optimization based on the node rotational dormancy is proposed. Firstly,the mathematical model of WSN energy optimization is established. The quantitative processing is using to transformed the multi-objective optimization problem to a single objective optimization prob-lem;Then,the algorithm of the node rotational dormancy is proposed. The experimental shows that the energy con-servation rate after optimizations of WSN by the algorithm in the paper are improved by more than 20%. The energy of Bottleneck nodes are more evenly distributed Therefore,it can effectively improve the performance of wireless sen-sor network,is a strong application energy optimization algorithm.
