基于RFID技术的室内定位算法优化方法研究

Study on indoor location algorithm optimization based on RFID technology

随着无线通信、物联网和计算机技术的蓬勃发展,室内无线定位技术正逐渐受到越来越多人的关注。在研究了几种基于射频识别技术的室内定位算法基础上,提出改进算法—基于牛顿插值和信号强度衰减模型插值的BVIRE定位算法(NTOR_BVIRE)。实验结果表明,改进算法在不额外增加参考标签的前提下,定位精度得到提高,达到了预期效果。

With the rapid development ol the wireless communication technology, the Internet ol things and computer technology, indoor wireless location technology gradually gets more and more people ’ s attention. Based on RFID location technology and studied several indoor localization algorithm, this paper points out an improved algorithm-based on the Newton interpolation and the signal intensity attenuation model interpolation BVIRE localization algorithm （ NTOR_BVIRE）. The experimental results show that the NTOR_ BVIRE algorithm, at the premise ol without an additional reference tags and not causing greater radio frequency interference, its localization accuracy is increased. It achieved the desired effect.
