能量利用效率问题是WSN领域中一个研究的挑战,因电源容量对其起着至关重要的作用.针对WSN中分簇路由算法产生能量空洞问题并且大的分簇中簇头任务过重,同时也为了提高WSN的能量利用效率,提出了一种无线传感器网络非均匀分簇双簇头算法——UDCH.该算法先综合考虑节点诸项信息(如节点剩余能量、节点到基站的距离、运行轮数的奇偶性等)来选举簇头,将整个网络划分为大小不等的簇;在规模大些的簇内,再选取副簇头.然后簇头再构造基于最小生成树的最优传输路径.通过一系列的仿真结果我们发现UDCH路由算法在WSN节约平衡节点能量消耗方面表现优良.
The issue of energy efficiency is a challenge in the field of WSN because power capacity plays a crucial role in it.Aiming at the problem of energy hole in clustering routing algorithm in WSN and the cluster head task in large cluster is too heavy, In order to improve the energy efficiency of WSN, a novel non-uniform clustering dual cluster head algorithm for wireless sensor networks (UCHCH) is proposed, which considers all the information of nodes (such as the residual energy of nodes, the distance between nodes and base stations, The number of rounds, etc.) to cluster head, the entire network is divided into clusters of different sizes; in the larger cluster, and then select the cluster head. Then cluster head reconfiguration based on the minimum spanning tree optimal transmission Through a series of simulation results, we find that the UDCH routing algorithm performs well in WSN saving the energy consumption of balanced nodes.
