Özet:

 

This paper tackles the RFID based tracking problem in an  obscured indoor environment.  The proposed solution is an integral  part of a navigation aid for guiding visually impaired people in a  store.  It uses RF signal strengths and is based on the Bayes Decision  Theory.  An observation vector is formed by received radio signal  strength indication values, transmitted from three transmitters at  distinct frequencies in the UHF band.  The indoor area is divided into  square grids, where each grid is considered as a class.  The problem  of tracking is expressed as classifying the observed radio signal  strengths to the most likely class.  A classification rule is  formulated by incorporating a priori assumptions appropriate for the  studied model.  The proposed approach is tested in a laboratory  environment.  The results prove that the proposed approach is  promising in tracking especially when the tracked person is guided by  a system.
