摘要
针对LEACH算法中节点能量消耗过快而容易死亡、簇头选举机制不合理及稳定周期短等问题,为提高网络稳定性,有效利用节点能量,提出了一种非完全分簇路由算法。该算法考虑节点剩余能量来选举簇头,利用基站能量充足的优势,建立非完全分簇,采用平面路由和分簇路由相结合的方式来实现数据传输,以均衡网络负载。仿真结果表明,该算法对比LEACH,网络稳定周期延长了29.48%,稳定周期占网络生命周期比例提高至72.53%,网络性能更优。
Aiming at improving network stability and energy efficiency, an incomplete clustered routing algorithm was proposed to solve problems that fast energy consumption and easy death of nodes and unreasonable cluster-head election and short network stable period in cluster routing protocol of LEACH. Considering remaining energy of nodes in cluster-head election, the proposed algorithm takes advantage of sufficient energy of base station to establish incomplete cluster. With combination of flat routing and cluster routing to transmit data, the algorithm can fairly distribute energy consumption in the entire network. Simulation results show that the networks performance better in terms of stable period by 29.48% and the proportion of stable period in lifetime to 72.53%.
