摘　　要：在采用多跳通信方式的分簇无线传感器网络中,接近sink点的簇头负担较重,容易过早耗尽能量而失效,造成网络分割,降低网络传输质量。针对该问题,在研究已有工作的基础上提出一种结合不等分簇和冗余簇头机制的路由算法。经仿真验证,该算法在延长网络生命周期、节约网络能耗和提高数据传输可靠性方面有较好的性能。In multi-hop Wireless Sensor Network（WSN） using clustered routing algorithm,the nearer to the sink node,the more load is put on the headers.As a result,headers near the sink node will quickly lose their energy and become unavailable which leads to network-partitioning and lower data transmission quality.In order to solve this problem,based on the analysis of existing researches,a new routing algorithm is proposed,which is based on both Unequal scaled Clusters and Redundancy of Headers（UCRH） algorithm.According to simulation results,UCRH algorithm overwhelms in prolonging network’s lifetime,reducing energy cost and supporting reliable data delivery.
