| 摘 要： | 为了有效平衡负载,满足大规模网络的需要,提出了一种基于能量感知的无线传感器网络层次型路由协议。该协议基于能量消耗模型,根据节点与基站的距离将网络中的节点划分为不同的层次。每层次内的节点轮流当选负责收集该层内所有节点数据的汇聚节点。汇聚节点的数据逐层转发和聚合,最后传送到剩余能量较大的一个汇聚节点——超节点,由其将数据发送到基站。汇聚节点变迁、超节点变迁机制用于均衡节点能量消耗,延长网络生命周期。NS2仿真结果表明,该协议可以有效节省能量,延长网络生存时间。

| Abstract: | To balance energy consumption and meet large-scale network need,an energy-aware hierarchical routing protocol(EHRP) for WSNs is presented.The sensor nodes are divided into different levels according to the distance between the nodes and the base station,based on radio energy dissipation model.Nodes in one tier are selected as sink node by turns which bear responsibility for collecting the data of the other nodes.The data of sink nodes is aggregated and forwarded to a sink node with the most residual energy ... |
