摘要
RFID技术是物联网的关键技术,为了解决射频识别技术中大量标签数据的防碰撞问题,提出了一种基于EPC-C1G2标准的Q值算法。该算法对原Q值算法中Q的取值方法进行了有效改进,同时结合标签分组算法,解决了在大量标签数据的情况下,如何保持较高的系统效率的问题。仿真结果表明,与传统算法相比,提出的改进算法不仅能够减少时隙数,提高时隙利用率,而且可以维持较好的系统吞吐率。
RFID technology is a key technology of the Internet of things.In order to solve the problem of anti-collisionin RFID technology with a large number of tag data,a new Q value algorithm based on EPC-C1G2 was proposed in this paper.In this algorithm,the method of Q is improved effectively.Otherwise,combined with the label grouping algorithm,the proposed method achieves higher system efficiency in a large number of tag data.The simulation results show that the proposed algorithm can not only reduce the slot number,improve the time slot utilization,but also maintain a good system throughput rate.
