一种基于查询前缀的快速抗冲突算法

Fast Anti-collision Algorithm Based on Query-prefix

基于阅读器发送的查询前缀和电子标签的响应后缀,提出一种新的射频识别(RFID)标签识别算法,用以解决RFID仲裁过程中的零标签响应问题。通过实验验证,与Memoryless抗冲突算法相比,该识别算法所需查询次数、查询信息量、标签响应次数及标签发送的信息量更少,从而降低功耗,加快标签识别速度,提高识别效率。

This paper presents a fast tag identification algorithm based on tag postfix and query-prefix to solve the zero-response problem in the process of Radio Frequency Identification（RFID） arbitration. Experimental results show that the algorithm needs less time of prefix broadcasting, tag response and the amount of information sent during the arbitration than Memoryless algorithm. So it is more efficient and shortens the time of arbitration process.
