摘　　要：针对低功耗自适应分簇(LEACH)路由协议中均匀分簇方式和簇头选择的不合理以及远距离数据传输过程中能量消耗过多的问题,提出了一种基于非均匀分簇的多跳路由算法LEACH-MRUC.在分簇过程中,该算法充分考虑了节点的能量及地理位置,同时采用非均匀分簇方式构建规模不同的簇结构;在数据传输过程中,簇头与基站之间采用单跳和多跳相结合的路由方式来进行通信.仿真结果表明,LEACH-MRUC算法既使得网络的能量消耗有效地得到均衡,又使得能量的利用效率得到显著提高,并且显著延长了网络的寿命.Concerning the deficiencies of Low Energy Adaptive Clustering Hierarchy （LEACH） routing protocol, approximately uniform cluster structure, unreasonable cluster-head nodes selection and also more than one cluster-heads consuming excessive energy in the process of long-distance communications, a mutil-hop routing algorithm based on uneven clustering is proposed. In the set-up phase, the remaining energy and the geographical position of nodes are fully considered, and it uses non-uniform clustering way to build cluster structure of different sizes. In the steady-state phase, a routing method with single-hop and multi-hop is also introduced to the communicate between cluster-heads and Base Station （BS）. Simulation results show that the algorithm effectively balances the energy consumption of networks, improves energy efficiency and obvious prolongs the network lifetime.
