摘　　要：针对路由算法对无线传感器网络wsn的能效影响很大,将AODV协议和TEEN协议进行优势组合并加以改进,提出一个阈值敏感的移动式基站按需路由算法.算法通过设置门限值和数据聚合减少了数据的传输,提高了网络的能效;采用移动式基站并配合按需路由,平衡了整个网络的能量消耗并节省了内存开销;采取CSMA传输方式和故障自动修复等方法,确保了网络的吞吐量.通过对网络能耗和活跃节点数进行仿真实验,结果表明,该算法具有优秀的综合性能.Routing algorithm has an important effect on wireless sensor networks. In the paper, TEEN protocal and AODV protocal are advantages combined and improved, a Threshold-sensitive Mobile Base Station On-demand Routing （TMBSOR） algorithm is presented. The algorithm sets the threshold and data aggregation to reduce the data transfer and improve network efficiency; uses mobile base station and with on-demand routing to balance the energy consumption of the entire network and save the memory overhead; takes CSMA transmission and automatic fault repair methods to ensure the network throughput. Energy consumption and active network nodes of the simulation results show that the algorithm has excellent overall performance.
