Abstract: The general situation and basic principle of Radio Frequency Identification(RFID) technology are introduced, according to which the nearest neighbor algorithm for indoor location system LARNDMARC based on RFID is proposed. Some factors influencing the positioning accuracy are taken into account. Moreover, an improved nearest neighbor algorithm is presented. It is proved this enhanced algorithm achieves better positioning accuracy than the existed one by conducting simulation methods.

Key words: Radio Frequency Identification(RFID), LARNDMARC system, indoor location, nearest neighbor algorithm
