摘要
提出了一种能量负载均衡高效的路由协议LEACH-improved节能算法。该算法通过加入间距因子、剩余能量因子和节点密度因子来改进阈值计算式,综合考虑节点剩余能量和地理位置选择簇首。此外,在不同WSN的应用场景中,根据剩余能量和地理位置对簇首的选择起到的作用大小不同,引入加权因子。仿真实验结果表明,改进后的算法有效地节省了网络的能量消耗,网络生命周期得到延长。
The improved energy-saving algorithm for the energy efficient and balanced protocol(LEACH-improved) was proposed.In the algorithm,the residual energy factor,the distance factor and the node density factor was added to improve the threshold formula.Moreover,in the various application scenarios of WSN,based on the different effects on the selection of cluster heads caused by the residual energy and geographical location,the weighting factor was introduced.Results of simulation experiments show that the improved algorithm can effectively reduce the network energy consumption and prolong the network lifetime.
