Abstract

Aiming to solve one of the serious problems of radio-signal strength (RSS) indoor positioning (namely, fluctuation of RSS values due to reflective waves), a novel indoor-positioning method based on RSS distribution modeling (called "RSS distribution modeling using the mirror-image method," RD-MMI), was developed and evaluated. With RDMMI, a model of RSS distribution is created by using measured RSS and considering reflective waves. RDMMI achieves an average positioning error of 4 m, which is better than that of conventional nearest-neighbor and trilateration methods by 50 to 60%. Furthermore, it accomplishes average positioning error of 5.4 m even with a small number of non-uniformly placed RSS measurements.

基于无线电信号强度分布的室内定位采用镜像法建模

针对无线电信号强度(RSS)室内定位中存在的一个严重问题(即反射波引起的RSS值波动)，提出并评价了一种基于RSS分布建模的室内定位新方法(即“基于镜像方法的RSS分布建模”RD-MMI)。利用RDMMI方法，利用实测的RSS并考虑反射波，建立了RSS分布模型。RDMMI的平均定位误差为4 m，比传统的最近邻法和三边法的定位误差提高了50% ~ 60%。此外，即使使用少量非均匀放置的RSS测量，该方法也能实现5.4 m的平均定位误差。
