| 摘 要： | 有源射频识别系统被广泛应用在现代物流、人员追踪与定位中。随着标签数增加,防碰撞问题越来越重要,目前有源标签防碰撞算法普遍比较简单,算法效率不高,而有源标签硬件资源丰富也为设计更好算法提供了可能。提出一种防碰撞算法,采用主从读写器包拯救机制和空闲时隙利用机制,并动态控制帧结束和标签接入,调整接入期收集期顺序。通过对归一化吞吐量的研究与仿真表明,这种新的防碰撞协议性能远优于目前已有研究成果。

| Abstract: | Active radio frequency identification（RFID）,as a novel wireless identification technology,is widely used in modern logistics,toll station,trace and orientation,and the anti-collision problem is deeply research in passive RFID.However,there exist some differences between active system and passive system,anti-collision problem in active system should be further studied.A mature anti-collision algorithm improved with master-slaver-packet-save mechanism and idle-slot-use mechanism is proposed,and simulation indicates that its inventory rate is improved a lot. |
