摘要

RFID系统在物品管理方面越来越受欢迎。在本文中，我们考虑了用于无源RFID标签识别的BFSA(基本框架槽位ALOHA)和DFSA(动态框架槽位ALOHA)协议，并重点研究了阅读器从所有标签中收集id所需的标签识别时间。我们提出了一个数学模型并对其进行了分析，以评估标签识别时间。我们还扩展了模型，以包括当插槽空闲而没有任何传输或发生碰撞时插槽长度被切断的情况。数值算例表明，采用DFSA协议并根据其使用情况调整插槽长度可显著缩短平均标签识别时间。

Performance Analysis of Tag Identification Time in Passive RFID Systems

RFID systems are getting popular for management of things. In this paper, we consider BFSA (Basic Framed Slotted ALOHA) and DFSA (Dynamic Framed Slotted ALOHA) protocols for identification of passive RFID tags, and focus on the tag identification time necessary for a reader to collect IDs from all the tags. We propose a mathematical model and analyze it to evaluate the tag identification time. We also extend the model to include the case that slot length is cut off either when a slot is idle without any transmission or when a collision occurs. Numerical examples show that average tag identification time is drastically decreased by using DFSA protocol and adjusting slot length depending on its usage.
