Abstract: 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.
