Open publisher page 0 citations

Abstract

Both identity and location are generally key information for indoor services.RFID is an automatic identification technology that enables tracking of people and objects.An obvious and interesting method is to localize RFID tags.However,in indoor environments,signals are harshly impaired and tags have very limited capabilities which pose many challenges for positioning them.This paper reviews the state-of-art of RFID positioning principles and localization technology,explains and classifies RFID localization techniques,and finally discusses the future trends.
