一种聚类区域自适应调整的WSN能耗均衡分簇算法

摘要

Based on the analysis of the LEACH protocol, this paper proposed an adaptive adjustment of cluster region WSN balanced energy clustering algorithm to the problems of LEACH protocol, caused uneven distribution of the cluster head of the local area network, cluster sizes and the energy consumption of the entire network were not balanced, and then shortened the network' s life. In the stage election of cluster, it considered the residual energy of head nodes and the distance between the pre-selected cluster-head and neighbor cluster-head as the criterion parameters. In the stage of joining-cluster, it considered the distance between the pre-join cluster-head and the base station, compared multiple data flows,and chose the optimal path of energy-saving. The simulation results show that the algorithm can balance the network' s energy effectively, and prolong the network lifetime significantly.%详细分析LEACH协议,针对LEACH协议随机产生簇头导致网络中出现局部区域簇头分布不均、簇的规模不一、整个网络能耗不均衡、网络寿命缩短等问题,提出了一种聚类区域自适应调整的WSN能耗均衡分簇算法.在算法的选举簇头阶段,将节点剩余能量、备选簇头与邻居簇头的间距相结合作为判据参数；在成簇阶段,将节点预加入的簇头到基站的距离考虑在内,比较多个数据流向,采用节能最优路径策略.仿真结果表明,该协议能够有效均衡网络各节点能耗,显著延长了网络生存时间.
