RFID系统，特别是工作在860- 960 MHz频率范围内的UHF RFID系统，被认为是连接物理世界和网络空间的桥梁。影响RFID系统普遍采用的一个主要挑战是标签冲突的有效解决和标签的快速识别。在本文中，时间效率被提出作为一个重要的指标来评估标签冲突解决协议的性能，并用于优化性能的常用的EPC Gen-2标签冲突协议的UHF系统。数值仿真结果表明，这种优化方法可以有效地提高协议的标签冲突解决周期。
RFID systems, especially the UHF RFID systems which work in the frequency range 860-960MHz, are regarded as a bridge to connect the physical world and the cyber space. One main challenge which affects the universal adoption of the RFID systems is the efficient resolution of the tag collision and the rapid identification of tags. In this paper, time efficiency is proposed as an important metric to evaluate the performance of tag collision resolution protocols, and is used to optimize the performance of the commonly used EPC Gen-2 tag collision protocol for the UHF systems. Numeric simulations are performed and it is verified that this optimization will facilitate the tag collision resolution cycle of the protocol.
