在密集射频识别(RFID)系统中，提出了一种新的既省时又节能的识别协议。该协议基于传统的M元冲突树(MCT)，其中涉及冲突的标签被分类到其他M个子树中。然而，与MCT不同的是，我们设计了一种传输机制，通过该机制，每个标签只以少量比特响应读取器进行冲突检测。该机制依赖于广泛用于RFID系统的冲突窗口和曼彻斯特编码。由于该机制大大减少了标签传输的比特数，从而在时间和能量消耗方面都提高了系统的整体性能。为了验证该机制的正确性，进行了性能分析。用蒙特卡罗方法进行了计算机模拟。然后将所获得的结果与MCT的结果进行比较，以证实所提出的协议的有效性。
This paper proposes a novel time- and energy-efficient identification protocol in dense radio frequency identifi-cation (RFID) systems. The protocol is based on the conventional M-ary collision tree (MCT) where tags involving a collision are classified into other M sub-trees. Nevertheless, different from the MCT, we design a transmission mechanism by which each tag only responds to the reader by a small number of bits for a collision detection. The mechanism is relied on a collision window and Manchester encoding that are widely used for RFID systems. Thanks to the mechanism, the number of bits transmitted by tags is significantly reduced, which improves the overall system performance in terms of both time and energy consumption. Performance analysis is investigated to validate the correctness of the mechanism. Computer simulations are also performed using Monte-Carlo method. The obtained results are then compared with those of the MCT to confirm the effectiveness of the proposed protocol.
