摘要
以无线传感器网络中的能量消耗模型为基础,提出了一种能量均衡的无线传感器网络分簇路由协议EECHS(energy-effficient cluster-head selection)。该协议通过节点的剩余能量和节点距离基站的距离来调节其成为簇首的概率,并进一步调节簇的大小。仿真结果表明,与改进后的DCHS协议相比,该策略使网络的生命周期和稳定周期分别提高了31%和45%以上。
This paper proposed a balanced-energy clustering routing protocol, based on the energy consumption model in wire- less sensor networks. This routing protocol adjusted the probability of a node to become a cluster-head, and controls the size of each cluster by using its residual energy and the distance between nodes to the base station. The simulation results show that, Compared with the improved DCHS protocol, the scheme improves the network life-time and stable-time up to 31% and 45% respectively.
