计算射频识别（CRFID）标签仅对收集的能量进行操作，并且已经成为各种无处不在的传感和计算应用的可行平台。由于其无电池特性，这些标签可以永久部署在难以到达的地方，消除了标签访问的可能性。在这种情况下，维护和升级标签的固件变得不可行，因为需要包括有线接口和基于PC的软件在内的编程工具来擦除、修改或重新编程微控制器单元的存储器。这种局限性使得对空中（OTA）方案的需求成为必要，该方案可以无线地重新编程或升级CRFID标签中的固件。在本文中，我们提出了R3-一种可靠的OTA重新编程方案，该方案符合EPC协议，并且不需要对RFID阅读器或CRFID标签进行硬件升级。我们展示了我们的计划在三个平台上，其中包括软件定义的以及基于芯片的CRFID标签，即WISP5.1和优化WISP（Opt-WISP），和蜘蛛标签，分别。该选择还包括基于闪存和基于帧的微控制器。我们广泛地评估我们的计划在几个指标，包括整体系统延迟，时间和能量开销，以及成功率与询问范围。我们预计我们奋进在实际情况下为CRFID代币提供OTA重新编程和固件升级的可行性。
Computational Radio Frequency Identification (CRFID) tags operate solely on harvested energy and have emerged as viable platforms for a variety of ubiquitous sensing and computation applications. Due to their battery-less nature, these tags can be permanently deployed in hard-to-reach places where the possibility of tag access is eliminated. In such scenarios, maintaining and upgrading the tag’s firmware becomes infeasible because programming tools, including wired interface and PC-based software, are required to erase, modify, or reprogram the microcontroller unit’s memory. Such limitations necessitate the demand for an over-the-air (OTA) scheme, which can wirelessly reprogram or upgrade the firmware in CRFID tags.In this article, we presentR3—a reliable OTA reprogramming scheme that is compliant with EPC protocol and requires no hardware upgrade to RFID reader or CRFID tag. We demonstrate our scheme on three platforms, which include both software-defined as well as chip-based CRFID tags, that is, WISP5.1 and Optimized WISP (Opt-WISP), and Spider tag, respectively. The selection also includes both the FLASH- and FRAM-based microcontrollers. We extensively evaluate our scheme in terms of several metrics, including overall system delay, time and energy overhead, and success rate in line with interrogation range. We foresee our endeavor to offer the viability of OTA reprogramming and firmware upgrade for CRFID tokens under practical situations.
