摘要: 作为物联网应用中的关键技术,射频识别(RFID)技术是近年来的热门研究领域。在大规模的RFID应用中,不可避免地会有标签识别的碰撞问题。以每个时隙传输数据的字节数以及搜索命令的发送次数作为参考指标,对已有算法进行分析比较,在已有算法的基础上提出一种改进的返回式二进制防碰撞算法,减少每个时隙数据的传输量和命令搜索次数,使得新的改进算法性能有较大的提升。

Abstract: As the key technology of Internet of Things applications,Radio Frequency Identification(RFID) is a hot research area in recent years.In the large-scale RFID applications,there will be inevitable collision of tags identification.As a reference to the number of bytes and the number of search instructions sent in a time slot,an improved return binary anti-collision algorithm is proposed to reduce data throughput and search instructions in per time slot.
