基于WiFi信号强度特征的室内定位系统设计
Design of Indoor Positioning System Based on WiFi Signal Intensity Characteristic
摘要
Abstract
Aiming at the problem that it is unable to get a more accurate location information indoors by using GPS positioning,this paper designs a positioning system using characteristics of WiFi signal strength based on Android platform,meets the demands of location information of indoor environment for people. The system consists of Android client,Tomcat server and MySQL database. Based on the general location fingerprint algorithm,this system adds MAC addresses to Access Point( AP) filtering,and gets the location fingerprint information by selecting fixed reference AP. On positioning stage,the weighting factor is added on the basis of the K-Nearest Neighbor( KNN) algorithm to further reduce the positioning error. Experimental results show that the system has the advantages of high precision and fast positioning, and it can achieve a good effect of indoor positioning.关键词
