Novell Hierarchy Topology Generation Algorithm of WSN

拓扑控制是无线传感器网络(WSN)中最重要的技术之一。在对现有拓扑控制方法分析的基础上提出了一种基于能量预测与代理簇头的分簇方法,通过区分热区的分簇方式减轻了漏斗效应;提出了代理簇头的概念,实现了簇结构的局部更新维护并降低了簇头选举算法的复杂性;仿真结果表明基于能量预测的簇头轮换更好地提高了网络负载的均衡度。

Topology control of wireless sensor networks is the focus study of wireless sensor networks application. Based on the analysis of existing topology control algorithm a dynamic clustering algorithm was proposed, which is based on energy forecast and agent-cluster-head. The clustering method characterized by distinguishing hot zones reduces the funnel effect in WSN; the introducing of agent-cluster-head not only makes the topology can be updated in partial area but also reduces the complexity of the cluster-head voting algorithm; the alternation of the cluster-head based on energy forecast balances the energy consumption of all sensor nodes.
