An anti-collision algorithm of RFID tags based on CDMA
Radio frequency identification (RFID) is rapidly come into our lives in recent years, and it is widely used in the areas of logistics, production, and transportation and so on. The technology of anticollision is a key of RFID. Most of the anticollision algorithms proposed before are based on TDMA. When the number of tags is very large, it can not well solve the problem. In this paper, an anticollision algorithm based CDMA is proposed, using the m sequence as the spreading code and combined with the S-ALOHA algorithm that is known as CMS-ALOHA algorithm. This paper analyzes the throughput of CMSALOHA, and gives the mathematical analysis. Experimental results show that this algorithm has good performance.
