An energy consumption balancing clustering algorithm based on LEACH

针对无线传感器网络LEACH协议及其改进算法中频繁重复分群带来的巨大能耗问题,提出了一种对稳定期数据传输模式进行改进的能耗均衡算法(ECBCA),减少了频繁重复分群所带来的能耗,提高了网络工作效率,延长了网络寿命。文中通过理论推导验证了算法的有效性,并通过仿真分析得到,采用ECBCA算法后,基站接收单位比特数据时网络所消耗的能量降低了13.3%;单位时间内基站接收的数据量提高了12.5%;网络寿命延长了14.7%。

After analyzing LEACH algorithm and related improved algorithms, an energy consumption balancing clustering algorithm （ECBCA） is proposed which is different from LEACH in data transmitting mode aimed at reducing high energy cost brought by frequent re-clustering. It is concluded in theory that ECBCA can decrease energy cost, increase network efficiency and prolong network lifetime. Simulation results show the effectiveness of ECBCA. Besides that, more energy can be saved while combining ECBCA with other related improved algorithms.
