Enhanced Filter-Based Relative Distance Estimation Method

摘要

Nowadays, beacon RSSI is utilized to estimate users’ locations. One of research suggests a distance estimation method in indoor environments. However, measured RSSIs are inaccurate in indoor environment. Therefore, a RSSI revision approach is required. This paper proposed a relativedistance estimation method (ReDEM-I) applying a RSSI filter (RF-II). The accuracy of measured RSSIs are increased by RF-II and then revised by ReDEM-I. The revised RSSIs are utilized to estimate users’ locations.
