摘要

基于wlan的定位方法很受欢迎，因为它们可以部署在任何地方，而无需额外的基础设施投资。其中，基于指纹辐射图的定位在离线(训练)阶段的指纹辐射图构建和在线(定位)阶段的设备位置估计方面得到了广泛的研究。本文提出了一种简单实用的无线局域网定位方法，该方法将无线局域网接入点(AP)位置数据库视为一个无线地图以减小其大小，无线地图在在线(定位)阶段以无监督的方式更新以保持最新，而不增加建设成本。在智能手机设备上进行的实验表明了所提出方法的有效性。

Efficient Radiomap Management for WLAN based Positioning System

WLAN-based positioning methods are popular because they can be deployed anywhere without additional infrastructure investment. Among them, positioning based on fingerprint radiomap has been widely studied in terms of fingerprint radiomap construction and device position estimation in offline (training) and online (positioning) phase, respectively. This paper presents simple and practical WLAN-based positioning method in which WLAN access point (AP) location database is considered as a radiomap to reduce its size and radiomap is updated in unsupervised manner in online (positioning) phase to maintain up-to-date without additional construction cost. Experiments carried out in smartphone device and shows effectiveness of the proposed methods.
