为了提高无线传感器网络节点定位精度，提出一种自适应加权定位算法。首先将距离加权因子拆分为独立加权因子，为独立加权因子匹配修正系数，修正系数根据测距距离做自适应调整，最后验证独立加权因子的自适应修正系数与基于接收信号强度的测距距离的数学关系。仿真试验结果表明，在同等测距误差前提下，独立加权因子的自适应修正能够显著降低平均定位误差，提高定位精度。%In order to enhance the node locating accuracy for wireless sensor network, the adaptive weighted locating algorithm is proposed. Firstly, the distance weighting factor is split into independent weighting factors, and the correction coefficients are matched for independent weighting factors, the correction coefficients are adapted in accordance with the distance measured, finally the mathematical relationship between the adaptive correction coefficient of the independent weighing factor and the distance measured based on received signal strength is verified. The result of simulation experiment shows that under the same level of distance measuring error, the adaptive correction of the independent weighing factor can reduce the average locating error significantly for improving the locating accuracy.
