RFID (Radio Frequency Identification) devices or tags, in their basic form, are useful as identification and proximity sensors. When augmented with other environmental sensors, RFIDs can also be turned into other wireless sensors. This project addresses ubiquitous RFID-based systems enabled by dense deployment of RFID tags/sensors, and RFID readers, where the readers are themselves inter-connected using a wireless ad hoc network. The goal of the readers is to access the RFID tag/sensor data and relay the necessary information to an application running on a central computer system. The project considers design and evaluation of protocols and algorithms to exploit redundancy and diversity in the form of tag multiplicity, reader multiplicity, antenna diversity, and multiplicity of operating modes for the tags. Communication protocols for tag-to-reader and reader-to-reader communication, as well as mechanisms for efficiently answering higher-level queries from applications are of particular interest.Expected results from the project include efficient protocols and algorithms to exploit redundancy and diversity in RFID systems, and demonstration of their efficacy by experimental or simulation-based methods. Results from the project will be disseminated via publications in conferences and journals. The project has significant potential for impact on practical utility of RFIDs, by improving the accuracy and efficiency of RFID access and queries. Potential applications include object tracking on factory floors, and sensing applications in home and office environments.

RFID（射频识别）设备或标签以其基本形式用作识别和接近传感器。当与其他环境传感器一起增强时，RFID也可以变成其他无线传感器。该项目解决了无处不在的RFID系统，通过密集部署RFID标签/传感器和RFID阅读器，其中阅读器本身使用无线ad hoc网络互连。阅读器的目标是访问RFID标签/传感器数据，并将必要的信息中继到中央计算机系统上运行的应用程序。该项目考虑了协议和算法的设计和评估，以利用标签多样性、阅读器多样性、天线多样性和标签操作模式多样性形式的冗余和多样性。标签到阅读器和阅读器到阅读器通信的通信协议，以及有效地回答来自应用程序的更高级别的查询的机制是特别感兴趣的。该项目的预期结果包括有效的协议和算法，以利用RFID系统中的冗余和多样性，并通过实验或基于模拟的方法证明其有效性。该项目的成果将通过在会议和期刊上发表的出版物传播。该项目通过提高RFID访问和查询的准确性和效率，对RFID的实际效用产生重大影响。潜在的应用包括工厂车间的物体跟踪，以及家庭和办公室环境中的传感应用。
