| 摘 要： | 基于信号强度（RSSI）的测距是一项低成本和低复杂度的距离测量技术,被广泛应用于无线传感器网络基于距离的定位技术中。基于RSSI测距的定位技术,通过线性回归分析对参数进行优化,引入高斯滤波模型,对RSSI值进行修正,提高了测距精度。采用泰勒级数展开对位置进行迭代计算,最后在TI的ZigBee平台上进行实验验证,通过仿真和实验验证了算法的可行性和优越性。与CC2431算法相比,该算法减小了定位误差,提高了定位精度。

| Abstract: | Distance measurement based on RSSI is a low-cost and low complexity distance measurement technique, and is widely applied in the localization technology of the range-based wireless sensor network. Based on the RSSI-based location technique, in order to improve the measurement accuracy, the linear regression analysis is used to optimize the parameters and Gaussian filtering model is introduced to amend the RSSI value. The Taylor series is used to make iterative calculation for po- sition. Finally, the experiment is verified on TI＇s Zigbee platform. The simulation and experiment verified the feasibility and superiority of the algorithm, reduced error and improved precision of the location compared with CC2431algorithm. |
