A New Method for Indoor Location Base on Radio Frequency Identification

In recent years, there has dramatic proliferation of research concerned with Radio Frequency Identification (RFID). The RFID technologies are getting considerable attentions not only academic research but also the applications of enterprise. One of most important issues of applications is the indoor position location. Many researchers have used varied technologies to perform the tracking of indoor position location. In this paper, we will purpose a new method using RFID tags to perform indoor position location tracking, too. This method uses Received Signal Strength (RSS) to collect signal strength from reference tags beforehand. Next, signal strength is used to set up Power Level areas of ranges by reference tags. And then, using signal strength from reference tags to match signal strength by track tags. Finally, when track tags is set up into indoor environments, it will find out the position of neighboring reference tags, and using arithmetic mean to calculate the location values. A preliminary experiment proves that our method provides a better precision than LANDMRC system. Key-Words: RFID, indoor location, RSS, Powel Level, localization, LANDMRC
