基于RFID的边界虚拟参考标签定位算法

摘要

介绍VIRE室内定位算法的原理,针对VIRE算法对边界标签定位准确度低的问题,提出边界虚拟参考标签定位算法BVIRE.该算法通过建立线性回归方程,在边界处加入边界虚拟参考标签.仿真结果表明,在不额外增加参考标签且不增大射频干扰的前提下,BVIRE算法较原算法使靠近边界处待定位标签的定位准确度得到较大提高.%This paper introduces the principle of VIRE algorithm for indoor location. For the positioning accuracy of boundary tags in VIRE positioning algorithm is low, BVIRE algorithm is proposed by using boundary virtual reference tags. BVIRE algorithm inserts some virtual reference tags on the boundary of the indoor environment by establishing a linear regression equation. Simulation results show that, BVIRE algorithm improves the positioning accuracy of boundary tags significantly without adding extra reference tags and radio frequency interference compared with VIRE algorithm.
