| 摘 要： | 分簇算法是有效解决无线传感器网络节点能耗受限与不同节点能量开销不平衡问题的主要方法之一.分簇算法中簇群成员节点和簇首的通信方式与簇群的拓扑结构决定整个簇群的能量消耗速度.通过建立簇半径与能量消耗关系模型,基于不同的约束条件和优化目标,优化簇半径取值使网络能耗达到最小化.方法仿真结果表明选取适当的分簇半径能够减少网络的能量消耗,均衡网络负载,延长网络的生存期,对无线传感器网络的能量优化设计有一定的参考价值.

| Abstract: | Clustering is one of effective methods for resolving node energy bottleneck and unbalanced consumption of clusters in wireless sensor network.Communications between cluster members and cluster heads decides energy consumption speed of all clusters in clustering.This paper presents a clustering radius and energy consumption model to optimizing the value of cluster radius for minimizing network energy consumption for different constraints and optimization goal.Simulation results demonstrate the scheme adoptin... |
