摘要
无线传感器网络协议LEACH中提到了分簇的思想,能够有效的减少节点在通信中的能量消耗,延长网络的生存时间.为了更有效的减少节点的能量消耗,延长网络的生存时间,可以在分簇的算法中采用能量均衡的思想,同时簇头收集数据后通过一棵路由树向汇聚节点发送数据.实验表明采用基于能量均衡的分簇算法的无线传感器有更好的整体性能和网络生存时间.
The cluster division algorithms mentioned in the LEACH protocol of wireless sensor networks can effectively reduce the power consumption of the communication node and extend the life-time of network.In order to more effectively reduce the energy consumption of nodes,extend the life-time of the network,it can adopt the energy balance thoughts in the cluster division algorithms,meanwhile the cluster-head node send data to sink node through a routing tree.Finical,experiment results showed that the wireless sensor network based on the energy balance algorithm performs better and has more life-time.
