模糊边缘检测无线传感器网络分簇算法

摘要

针对传统分簇算法簇头选举仅单一考虑节点位置或能量分布的问题,提出了一种基于模糊边缘检测的无线传感网络分簇算法,该算法综合考虑拓扑边缘信息和节点能量分布,根据网络能量分布情况调整带宽内边缘节点参与簇头选举的概率.仿真结果表明,该算法簇头选举相对于LEACH算法分布更加合理,有效延长网络生命周期.%Aiming at the problem that traditional clustering algorithms consider node location apart form energy distribution, this paper proposes a clustering algorithm based on fuzzy boundary detection, which took into account topological boundary information and node energy distribution, and adjusted the probability that boundary nodes participate in cluster head selection according to the network energy distribution. Simulation results indicate that this algorithm can detect boundary nodes of certain boundary bandwidth, make more sensible cluster head distribution than LEACH, and obviousry extend the network lifetime.
