摘要
研究了基于信号强度模型的室内定位技术 .通过运用线性回归、补偿式线性回归和多元回归方法 ,利用仿真数据建立了信号强度模型 .为了理解定位误差和信号强度误差之间的关系 ,对这种构模方法作了分析 ,得出的一些重要结论有助于确定接入点 (AP)的部署点及评估定位误差的范围 .最后 ,基于IEEE80 2 .11bMAC的典型参数进行了仿真试验 .
We have investigated the indoor geolocation based on signal strength modeling. Linear, compensated linear, and multiple regression methods are applied to set up signal strength models by using simulated data. We also analyze this modeling method to better understand the relation between the location error and the signal strength error. Some important results are obtained to help us determine proper placement of Access Points (AP) and evaluate the range of location error. A simulation experiment is conducted based on typical parameters of IEEE802.11b MAC.
