锁位式RFID双前缀探针防碰撞算法
Lock-bit RFID dual prefix probe anti-collision algorithm
摘要
Abstract
In view of the problem that the recognition efficiency of the system is reduced due to the tag collision in the highly dense radio frequency identification (RFID) system,this paper proposed a lock-bit dual prefix probe anti-collision algorithm.Based on the dual prefix probe anti-collision algorithm,the new algorithm took advantage of the features of Manchester encoding,through lock-bit instructions lock the collision bit,extracted the collision information,and only transmitted part of the information during the subsequent identification process,combined with idea of dual prefix query,in reducing collision slots,while reducing the amount of data transmission.In the design process,it considered three important performance indexes,which were the total timeslots,throughtput and identification efficiency.Theoretical analysis and computer simulations show that the new algorithm has higher recognition efficiency and throughput than the existing algorithms,and is more suitable for RFID identification system.关键词
