摘　　要：提出基于三步策略的信标传输功率的调整算法。针对信标预定的z-字型路径,TSATP算法对信标传输beacon包的传输半径进行估算,并依据传输半径调整传输功率,进而降低能耗。仿真结果表明,提出的TSATP算法降低了信标和传感节点的能耗。Three-step strategy based adjusting transmission power(TSATP)algorithm was proposed.For deterministic z-path traveled by the single beacon,TSATP algorithm estimated the transmission radius,and adjusted the transmission power based on the transmission radius in order to reduce consumed power.Simulation results show that TSATP algorithm successfully reduce the consumed power of beacon and sensor nodes.
