摘要
摘要:该文提出一种基于Mann-Whitney秩和检验的无线局域网(WLAN)室内映射与定位方法。该方法首先根据实际定位精度需求对目标区域中的运动路径进行分段，同时基于Mann-Whitney秩和检验方法合并相似运动路径片段；然后，利用一种基于相似接收信号强度(RSS)序列片段的信号聚类算法，保证同一聚类中RSS样本的物理邻接关系；最后，通过骨干节点的扩散映射，建立物理与信号空间的映射关系，实现对运动用户的定位。实验结果表明，相比于已有WLAN室内映射与定位方法，该文方法在无需运动传感器辅助和构建位置指纹数据库的条件下，能够实现更高的映射与定位精度。

Abstract:The Mann-Whitney rank sum test based Wireless Local Area Network (WLAN) indoor mapping and localization approach is proposed. Firstly, according to the localization accuracy requirement, this approach performs the motion paths segmentation in target area, and meanwhile merges the similar motion path segments based on the Mann-Whitney rank sum test. Then, a signal clustering algorithm based on the similar Received Signal Strength (RSS) sequence segments is adopted to guarantee the physical adjacency of the RSS samples in the same cluster. Finally, the backbone nodes based diffusion mapping is used to construct the mapping relations between the physical and signal spaces, and the motion user localization is consequently achieved. The experimental results indicate that compared with the existing WLAN indoor mapping and localization approaches, the proposed one is able to achieve higher mapping and localization accuracy without motion sensor assistance or location fingerprint database construction.
