Abstract

This paper focuses on the WLAN-based indoor location by taking into account the contribution of each hearable Access Point (AP) in the location estimation. Typically, in many indoor scenarios of interest for the future location services, such as malls, shopping centers, airports or other transit hubs, the amount of hearable APs is huge and it is important to find out whether some of these APs are redundant for the purpose of location accuracy and may be dropped. Moreover, many APs nowadays are multi-antenna APs or support multiple MAC addresses coming from exactly the same location, thus it is likely that they may bring little or no benefit if keeping all in the positioning stage. The purpose of our paper is to address various significance measures in WLAN-based location and to compare them from the point of view of the accuracy of the location solution. The access point significance is studied both at the training stage and at the estimation stage. Our models are based on real measurement data.
无线局域网定位中的接入点重要性度量
本文主要研究基于无线局域网的室内定位问题,考虑每个可听接入点(AP)在位置估计中的贡献。通常,在许多对未来定位服务感兴趣的室内场景中,如商场、购物中心、机场或其他交通枢纽,可听ap的数量非常大,重要的是要找出其中一些ap是否为了定位准确性而冗余并且可能被丢弃。此外,现在许多ap都是多天线ap,或者支持来自完全相同位置的多个MAC地址,因此如果将所有ap都保留在定位阶段,可能会带来很少或没有好处。本文的目的是讨论基于无线局域网的定位中的各种重要度量,并从定位解决方案精度的角度对它们进行比较。在训练阶段和估计阶段分别研究了接入点的显著性。我们的模型是基于真实的测量数据。
