摘要:
为了提高无线传感器网络低功耗自适应聚类路由算法(LEACH)的能量利用效率,首先建立了该算法的通信模型,得出了在簇形成阶段和数据采集阶段网络节点的能量消耗.其次分析了传感器节点每轮只采集一次数据和每轮采集多次数据这2种不同情况下所消耗的能量.最后通过对比节点在具有相同初始能量条件下采集信息量的差异,理论上推导出了最优化的数据采集方案,使得无线传感器网络节点在能量使用效率上有了较大提高,并通过仿真实验说明了它的可行性和正确性.实验结果表明,与每轮只采集一次数据相比,最优化采集方案能在其基础上提高33%的能量利用效率.
Abstract:
To improve the energy efficiency of low energy adaptive clustering hierarchy(LEACH), the communication model was established firstly and the energy consumption in the cluster forming phase and data collection phase were obtained. Secondly, the energy consumption was analyzed under two different conditions, i. e. , collecting data one time per round and collecting data several times per round. At last, the optimal data collection scheme was designed through computing optimal times of data collection. Experimental results show that our scheme improves significantly energy efficiency of the total networks. Compared with collecting data one time per round, our scheme can improve energy efficiency by 33%.
