针对无线传感网络中测距和定位算法复杂、精度不高的问题，提出了一种基于蚁群算法的循环定位算法。首先，利用接收信号强度指示（RSSI）方法测量距离，并建立信号衰减模型来计算测距公式。然后，利用循环定位算法对8个锚节点进行循环定位，将定位结果的平均值作为盲节点的最佳位置。最后，将该算法与加权质心定位算法和三边测量法进行对比，实验结果表明，循环定位算法的定位精度和稳定性更佳。

To overcome the problems of complez algorithm,less accurate in the wireless sensor networks(WSNs) ranging and locating,the loop localization algorithm is proposed based on ant colony algorithm. Firstly,the ezperimental data is measured by the received signal strength indication(RSSI)method,and the signal attenuation model is established to calculate the distance formula. Secondly,the cycle localization algorithm is used to locate the eight anchor nodes cyclically and the average of the eight results as the best position of the blind node. Finally,the algorithm proposed is compared with the weighted centroid localization algorithm and three sided measurement,and the ezperimental results show that the cycle localization algorithm has higher positioning accuracy and stability.
