Abstract:
This paper describes briefly the composition and operation principles and digital collision of Radio Frequency Identification （RFID）. In accordance with technical requirements and application features of RFID, this paper advances a method of dynamic ALOHA base on TDMA for anti-collision of RFID, analyzes and demonstrates the operation principles, feasibility and implementation process. This method dispenses with adding hardware, so it has such characteristics as less application cost and high adaptability.[著者文摘]
