Abstract: With the rapid development of RFID technology, integrated with micro sensors’ tags are become increasingly popular. Reason is that they can not only provide their unique IDs, but also report dynamic, real-time information about the status of the homologous tags or the conditions of the environment, which is beneficial to many practical applications. For such application, this paper studies how to categorically collect such information quickly and efficiently, the core idea of this protocol is to use the conflict time slot of the same category tags, and then complete the tags information collection process. Theoretical analysis and simulation results show the effectiveness of protocol, compared with other methods, the protocol greatly saves the consumed time.

摘要： 随着RFID技术的快速发展，集成有微型传感器的标签受到了越来越广泛的关注。原因是其不仅能够提供标签的ID号，而且还可以实时、动态地提供它附着的物品的状态或所处环境的条件状况，而这对许多应用领域起到了很重要的作用。针对此类应用，研究了如何快速高效地分类别收集集成有微型传感器的标签信息，该算法的核心思想是摒弃传统避免冲突时隙的方法，而是通过利用冲突时隙将不同类别的标签同时分类，最后完成标签信息收集的整个过程。理论分析和仿真结果均表明了该算法的高效性，相对比于其他信息收集的方法，该算法大大节约了所消耗的时间。
