以无线多跳传感器网络中的能量消耗模型为基础,提出一种能量均衡分簇策略.该策略利用几何规划原理,通过节点的能量水平和距离向量来调节其成为簇头的概率,并进一步调节簇的大小.仿真结果表明,与HEED(hybrid,energy-efficient,distributed clustering approach)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21%和40%以上.
A balanced-energy clustering scheme(BECS) is proposed which is based on the energy consumption model in multi-hop wireless sensor networks.According to the geometric programming theory,this scheme adjusts the probability of a node to become a cluster-head,and controls the size of each cluster by using the energy level of the cluster-head and the distance vector from the sink.The simulation results show that,compared with the HEED(hybrid,energy-efficient,distributed clustering approach) protocol,this scheme improves the network life-time and stable-time up to 21% and 40% respectively.
