由于无限的可能性和低成本，射频识别（RFID）系统被用于各种应用中，以唯一地识别物理对象。RFID系统的操作通常涉及这样一种情况，其中在单个读取器的询问区域中同时存在多个标签。标签可能会相互冲突和抵消，导致标签ID的重传，从而导致带宽浪费和总延迟的增加。此外，物理上彼此靠近的读取器可能会干扰彼此的操作。必须最小化这种读取器冲突以确保RFID系统的当前操作。本文的主要重点是调查冲突解决协议的多址通信和算法，计算如何最大限度地减少阅读器到阅读器的干扰。针对RFID系统中的冲突问题，对现有的协议进行了比较. (c)2006 Elsevier B.V.保留所有权利。
Due to the limitless possibilities and low cost, Radio Frequency Identification (RFID) systems are used in a variety of applications to uniquely identify physical objects. The operation of RFID systems often involves a situation in which numerous tags are present in the interrogation zone of a single reader at the same time. The tags can collide and cancel each other out, leading to retransmission of tag IDs that results in wastage of bandwidth and an increase in the total delay. Besides, readers physically located near one another may interfere with one another's operation. Such reader collision must be minimized to ensure the current operation of the RFID system. The main focus of this paper is to survey the collision resolution protocols for multi-access communication and the algorithms that calculate how to minimize reader-to-reader interference. A comparative view of surveyed protocol was concluded for the collision problem in RFID systems. (c) 2006 Elsevier B.V. All rights reserved.
