On the bases paring several range-based node location algorithms methods,this paper adopted a TDOAlocation algorithm which was based on the theory of range-based higher accuracy,and then made revises about algo-rithm in realistic condition. In order to get the arrival time difference of sound signal through measurement,-pletedⅡR filter and amplitude analysis. The simulation and experimental results show that the TDOA location algorithmof this design greatly reduces the amount of calculation and has accurate location results,which is words:wireless work;location;TDOA;ⅡR filter;amplitude :7230;6150P;6210;7110 doi: / - TDOA 无线传感器网络节点定位算法张会新1,2,陈德沅1,2,彭晴晴1,2,史 磊3(1.
