摘要
基于接收信号强度(RSS)的WiFi室内定位技术由于其成本低、易部署的特点成为近年来的一个研究热点。基于RSS的WiFi室内定位由于受到室内环境复杂、动态变化性强的特性,位置估计精度和可靠度较低,因此本文提出了一种新的位置融合定位策略进一步改善基于RSS的WiFi室内定位的精度。新的位置估计策略融合三种AP选取策略的位置估计结果,试验结果表明,新提出的位置融合定位策略能够提高位置估计的精度,同时保证定位结果的可靠性,其整体定位性能更优。
WiFi indoor location technology based on RSS(Received Signal Strength)has become a research hotspot in recent years due to its low cost and easy deployment.WiFi indoor location based on RSS due to indoor environment is complex,dynamic characteristics,position estimation accuracy and reliability is low,so this paper proposes a new fusion positioning strategy to further improve the position of the WiFi indoor positioning precision based on RSS.Three kinds of AP fusion strategy selection strategy position estimation results to estimate the new position,the test results show that the new proposed position fusion positioning strategy can improve the accuracy of position estimation,reliability and guarantee the positioning results,and the overall performance is better.
