Zhonghua Wang · Coal Technology · 2011
Radio Frequency Identification(RFID) technology started to be developed in 1980s.In RFID system,in order to resolve the problems of collision,certain collision algorithm must be carried out.Binary Search Collision Algorithm,one kind of TDMA(Time Division Multiple Access) algorithm,has one of the highest identification rates,Therefore,it is the most frequently used collision algorithm in RFID system.This paper briefly introduces the principles of commonly-used collision algorithms.After that,the principles and implement processes of Binary Search Collision Algorithms are presented.Finally,research and preparation are conducted as for the efficiency of two algorithms and thus lead to suggestion of algorithm improvement.
