| 摘 要： | 对于大规模的传感器网络而言,生存时间是衡量网络性能的关键指标.为了更有效地延长传感器网络的生存时间,提出了一种新的基于距离能量指标和主副簇头策略的分簇算法.该算法利用Voronoi多边形实现基于节点分布的自适应成簇,以获得平衡的簇区域;提出新的距离能量级作为簇内簇头轮换的标准从而平衡簇能量分布,并引入主副簇头机制避免簇的"假死亡",增强网络鲁棒性,进一步延长网络的生存周期.理论分析和仿真实验表明,这种成簇机制能有效地延长网络的生存周期,获得更多的数据量.

| Abstract: | For large scale sensor network,the life is very important for the performance of network.Aimed at how to prolong the life of sensor network,a new clustering algorithm based on distance-energy and master-vice cluster head is proposed.Voronoi polygon is used to realize the adaptive clustering based on the distribution of nodes and gain balance clusters.In order to balance the distribution of energy,distance-energy level is proposed as the basis of cluster head rotation in cluster area.Master-vice cluster head... |
