摘　　要：本文首先分析了LEACH这种经典的无线传感器网络路由协议存在的一些问题,指出了它的优缺点,在此基础上提出了一种新的LEACH协议改进算法——DR-LEACH,该算法主要通过航位推算方法来减少数据收发次数,进而达到减少能耗的目的。通过计算和NS2仿真实验表明,DR-LEACH算法在不影响数据精度的前提下,延长了网络生存周期,有效的证明了该算法的可行性。Some existing problems of wirless sensor network routing protocol are briefly analyzed in the paper firstly,which indicates some advantages and disadvantages. Based on the work done above,the essay proposes a LEACH protocol improved algorithm based on dead-reckoning method. Numbers of data received in DR-LEACH, it has proposed based on dead-reckoning method,and energy consumption can be reduced. Through computation and simulation used NS2,period of network life is extended and the precision of data can’t be affected in DR-LEACH algorithm,effectively demonstrated the feasibility of the algorithm
