基于WiFi的室内定位中AP选择方法研究

摘要

该文对现有室内定位中的AP（Access Points）选择算法进行了研究。首先，从时间、地点、方向等方面对AP信号造成的影响进行了实验分析，得出AP选择的重要性。其次，从国内外的研究现状出发，对基于WiFi的室内定位中AP选择算法进行了分类和对比分析，讨论算法的优缺点，分析显示室内定位算法的研究注重定位精度和能源消耗之间的平衡，最终得出结论。%The paper examines the AP selection algorithms in existing indoor location schemes. Firstly, it looks into the impacts such aspects as time, location and orientation have on AP signal through experiments, showing the importance of AP selection. Secondly, based on the research both at home and abroad, this paper categorizes and compares the AP selection algorithms in Wi-Fi-based indoor location and discusses their strengths and weaknesses. The analysis shows that research on indoor location algo-rithms place a great emphasis on the balance between location accuracy and energy consumption. Lastly the paper arrives at con-clusions.
