摘　　要：为了提高高速公路路安全监控无线传感器网络中节点能量的利用效率,并延长网络生存时间,提出一种基于同心圆路由树的路由选择算法。该算法以最小功率进行路由发现,采用短距离的多跳数据传输,引入对簇内节点分级的机制,提高网络能量利用率。仿真结果表明:采用该算法比与采用同类能量感知路由算法相比,所得网络生存时间更长,平均能耗更小。Concentric circles tree based on routing algorithm was proposed to improve the nodes’ energy efficiency and extend the lifetime of wireless sensor network for high-speed railway（WSN-H）.The algorithm finds the route with minimum power,uses short-distance multi-hop data transmission and introduces the cluster node classification mechanism to improve network energy efficiency.The simulation results show that the proposed algorithm has a longer network lifetime and a smaller average energy consumption than the same energy-aware routing algorithm.
