| 摘 要： | 延长网络的生命周期、有效降低节点的能量消耗是无线传感器网络(WSNs)路由研究的重点;针对LEACH协议的簇头选举不合理和和簇成员仅依据自身通信代价选择簇头导致节点能耗不均衡,网络能量利用率低的问题,提出了一种基于多权值的低能耗分簇算法,它综合考虑了候选簇头的剩余能量、节点已当选簇头次数和当前网络簇头个数等多个因素;仿真实验表明,改进协议有效地降低了节点的总能量消耗、提高了网络节点的存活数目,延长了网络的生命周期。

| Abstract: | Prolonging the life time of the networks and reducing the energy consumption of the nodes are the central topic for research on WSNs routing protocols.Aiming at the problem of unbalanced energy consumption of nodes and low energy utilization because of irrationality of choosing cluster head and the nodes only consider their own communication cost in the formation of the cluster in LEACH,a lower power consumption clustering protocols based on the multi-weight is proposed,which take into consideration many fa... |
