摘要： 运用TDOA方法对节点定位时，需要对节点测距。由于时间精度及硬件的限制，其定位精度有时不能达到要求。针对这一问题，提出一种对TDOA定位方法的改进算法，减小了由于测距产生的定位误差。并通过仿真证明了改进算法的优越性。

Abstract: Estimate the randomly deployed nodes position of a Wireless Sensor Network（WSN） by TDOA（Time Difference of Arrival），determining the distance of the nodes is needed.Sometimes，the localization accuracy of TDOA can not meet the requirement.Against this problem，an improvement algorithm on TDOA localization is addressed and the improvement algorithm reduces the error of the localization.At last，the advantage of the improvement algorithm is proved by the simulation.
