Abstract

The performance of RFID anti-collision protocols that are based on framed ALOHA depends on a transmission scheme that controls access to the shared channel. In this paper, we outline the characteristics of the RFID domain that impact the performance of such transmission schemes and compare four different transmission strategies. A novel technique introduced in this paper that recursively estimates the backlog on a slot-by-slot basis exhibits a superior performance in our simulations. The results also illustrate that our implementation of the Q algorithm proposed in (EPCglobal, 2005) only performs well, if the frame size changes are restricted to incremental updates
基于ALOHA框架的RFID协议传输方案的比较
基于框架ALOHA的RFID防碰撞协议的性能取决于控制对共享信道访问的传输方案。在本文中,我们概述了影响此类传输方案性能的RFID域的特征,并比较了四种不同的传输策略。本文介绍了一种基于逐槽递归估计积压的新技术,在我们的仿真中显示了优越的性能。结果还表明,我们在(EPCglobal, 2005)中提出的Q算法的实现只有在帧大小变化仅限于增量更新时才表现良好
