| 摘 要： | 针对传感器网络存在的节点能耗过快问题,提出了一种新的分簇路由协议EEGC。该协议底层拓扑采用分簇及簇内部分覆盖算法,有效地降低了网络能耗。上层拓扑采用近簇头单跳通信、远簇头多跳通信的方式,缓解了内环簇头能耗过快的问题。同时,以簇头剩余能量决定簇及簇间路由的重构,进一步提高了控制消息的效率。仿真验证表明,EEGC协议的网络寿命明显优于LEACH。

| Abstract: | Considering the efficiency of energy consumption in wireless sensor networks,in this paper,a new clustering routing protocol EEGC is proposed.It saves the energy by clustering and the cluster coverage algorithm on the bottom level.Then on the top level,message is transmitted in single-hop when cluster-head was near the sink node and in multi-hop when cluster-head is far away from the sink node,which could relieve the problem that cluster heads closer to the sink node tend to die earlier.Furthermore,cluster ... |
