中文摘要: 介绍了VIRE算法和BVIRE算法的定位原理. 在BVIRE算法的基础上, 提出了一种基于邻近参考标签的权值的改进算法(简称WBVIRE算法). 该算法通过改进最近邻参考标签与待定位标签的信号强度的差值, 重新设定邻近参考标签的权值计算方法, 以得到更加准确的待定位标签的坐标, 从而提高BVIRE算法的室内定位精度. 实验结果表明, WBVIRE算法明显提高了室内定位精度.

中文关键词: 室内定位信号强度邻近参考标签的权值精度

Abstract:The paper introduces the principles of VIRE algorithm and BVIRE algorithm for indoor location. On the basis of BVIRE algorithm, the paper proposed an improved algorithm based on the weights of the neighboring reference tags (Referred as WBVIRE algorithm). The new algorithm is reset the calculation method of the weights of neighboring reference tags by improving the difference of RSSI between the positioning reference tags and the neighboring reference tags. Then the system calculated a more accurate coordinates to be positioned tags and made better the indoor location accuracy of BVIRE algorithm. Experimental results show that the WBVIRE algorithm significantly improves the indoor location accuracy.
