摘　　要：针对多跳层次性路由算法中存在的距离基站较近的节点因数据通信负载过重而导致死亡速度过快的问题,提出一种无线传感器网络跳数优化非均衡路由(Hop Optimized Unequal Clustering Routing,HOUCR)算法。HOUCR建立基于最优跳数的路由路径,减小每回合网络能量消耗;通过能量均衡产生非均衡的簇,解决"热点"问题。仿真实验表明,HOUCR能够减小并均衡网络能量消耗,延长了网络寿命。In multi-hop clustering routing algorithm for wireless sensor networks, nodes close to base station die over quick for heavy traffic load. A hop optimized unequal clustering routing algorithm for wireless sensor networks is proposed. HOUCR establishes routing path based on optimal hop counts to reduce network energy consumption in each round. It forms unequal cluster to realize energy balance and solve the ＂hop spot＂ problem. Simulation re- sults show that, HOUCR can reduce and balance network energy consumption, prolong network life-time.
