摘要

摘要: 在被动式射频识别（Radio frequency identification，RFID）系统中，即使有多个标签同时向阅读器发送信息，捕获效应也能使其中一个标签被阅读器成功识别. 而且，捕获效应还会导致标签漏读.为防止标签漏读和进一步提高捕获效应下的识别效率，我们提出一种新的防冲突协议，该协议采用自适应和分配技术来减少标签间冲突.其优点在于，可合理地分配冲突标签和隐藏标签，从而提高识别效率. 计算机仿真结果显示，在捕获效应发生的环境下，本文协议的识别效率优于现存协议.

Abstract: In passive radio frequency identification (RFID) systems, capture effect will make a tag's signal decoded even when multiple tags simultaneously transmit their signals to a reader. Besides, capture effect will make the reader miss some tags. In this paper, we propose a novel tag anti-collision protocol for capture effect to avoid missing tags and further enhance the efficiency of identification. The proposed protocol adopts an adaptive and allocation technique. The advantage of the adopted techniques is to reasonably allocate slots to hidden tags by capture effect and collided tags, reduce collision between the tags and thus enhance the identification efficiency. Computer simulation results show that the proposed protocol's efficiency outperforms other existing protocols under a capture effect environment.
