The objective of this research is to formulate design principles for and demonstrate, via prototyping, the feasibility of a new sensor network of everyday objects based on radio frequency identification (RFID) system components. The vision exploits the advantages of RFID while addressing two key challenges, namely the lack of sensor integration onto RFID tags and the need for careful redesign of the transceivers (i.e, down and up links as well as the multiple access protocol). Central to the success of the proposed research are two key advances already in place at University of Washington-Intel Research Labs. First, a new class of passive RFID tags, called wireless identification and sensing platforms (WISPs), integrated with appropriate sensors and designed for enhanced power harvesting are available. Second, a software-defined reader (SDR) that allows innovation of link and medium access control (MAC) protocols is available.With respect to intellectual merit, the research pursues an integrated systems solution to RFID network design at various interacting levels of abstraction. As an example, the research considers coupled circuit and electromagnetic simulation that characterizes the back-scattered uplink signal at the reader, which in turn can suggest link and MAC layer components, such as modulation and coding as well as collision avoidance dedicated to interference mitigation.With respect to broader impacts, the research has the potential to accelerate academic research into RFID networks via freeware distribution of the SDR code and limited availability of WISPs as well as dissemination via topical tutorials. Successful execution of the project can move RFID technology from its intended application of reading tag IDs within a supply chain environment toward the more ambitious goal of realizing a ubiquitous "internet of things."

本研究的目的是制定基于射频识别 (RFID) 系统组件的新型日常物体传感器网络的设计原则，并通过原型设计演示其可行性。 该愿景利用了 RFID 的优势，同时解决了两个关键挑战，即 RFID 标签上缺乏传感器集成以及需要仔细重新设计收发器（即下行和上行链路以及多路访问协议）。 这项研究取得成功的核心是华盛顿大学英特尔研究实验室已经取得的两项关键进展。 首先，一种新型无源 RFID 标签，称为无线识别和传感平台 (WISP)，与适当的传感器集成，专为增强能量收集而设计。 其次，软件定义阅读器 (SDR) 允许链路和介质访问控制 (MAC) 协议创新。就智力价值而言，该研究寻求在各种交互抽象级别上为 RFID 网络设计提供集成系统解决方案。 例如，该研究考虑了耦合电路和电磁仿真，它们表征了读取器处的反向散射上行链路信号，这反过来又可以建议链路和MAC层组件，例如调制和编码以及专用于干扰减轻的冲突避免。就更广泛的影响而言，该研究有可能通过 SDR 代码的免费软件分发和 WISP 的有限可用性以及通过主题教程进行传播来加速 RFID 网络的学术研究。 该项目的成功执行可以将RFID技术从其在供应链环境中读取标签ID的预期应用转向实现无处不在的“物联网”这一更雄心勃勃的目标。
