推动物联网（IoT）快速发展的射频识别（RFID）已经是一种新兴技术，并且广泛部署在诸如仓库管理、供应链管理和社交网络的各种应用中。在这样的应用中，可以通过将低成本的RFID标签贴在物体上并对其进行仔细监控来有效地管理物体。因此，丢失的物体可以由RFID系统中的读取器识别。大多数现有的丢失标签识别协议考虑了所有标签的ID对于读取器是已知的理想场景，其忽略了系统中可能存在一些具有未知ID的标签（称为未知标签）。在本文中，我们调查的问题，有效地识别丢失的标签与一个预定义的可靠性大规模的RFID系统与未知的标签。我们首先提出了一个基本的高效和可靠的丢失标签识别协议称为B-ERMI。然后，我们提出了一个增强的协议称为E-ERMI，以进一步提高效率。我们提出的ERMI协议的参数进行了优化，以尽量减少执行时间。我们还进行了大量的模拟评估所提出的ERMI协议和模拟结果表明，ERMI协议优于其他现有的。
Radio frequency identification (RFID), which promotes the rapid development of Internet of Things (IoT), has been an emerging technology and widely deployed in various applications such as warehouse management, supply chain management, and social networks. In such applications, objects can be efficiently managed by attaching them with low-cost RFID tags and carefully monitoring them. The missing objects, therefore, can be identified by the readers in the RFID system. Most of prior missing tag identification protocols consider the ideal scenario that all the tags’ IDs are known to the reader, which ignore that some tags with unknown IDs, called unknown tags, may be present in the system. In this paper, we investigate the problem of efficiently identifying the missing tags with a predefined reliability for large-scale RFID systems with unknown tags. We first propose a basic efficient and reliable missing tag identification protocol called B-ERMI. Then we propose an enhanced protocol called E-ERMI to further improve the efficiency. The parameters of our proposed ERMI protocols are optimized to minimize the execution time. We also conduct extensive simulations to evaluate the proposed ERMI protocols and the simulation results illustrate that the ERMI protocols outperform other existing ones.
