CSR: Small: Towards Autonomous, Ultra-Low Power RFID-Scale Sensing Systems

该项目对下一代基于采集的rfid规模传感技术的设计、实现和部署进行了跨学科、跨层次的基础研究。这项工作涉及对CRFID硬件/软件接口的研究，包括能源管理、数据存储系统和能源感知计算，以推进对零功耗普及设备的认识和理解。它解决了几个基本的研究挑战，包括：1)在能量收集，存储和使用方面的权衡，可以使RFID传感器更可编程，同时不影响能源效率；2)在低电压下利用概率闪存写入的数据存储系统，可以容忍频繁的电源中断；3)能源管理技术，暴露不确定性驱动的能源管理接口，并以收集感知的方式安排任务。预计该项目将在设计、开发和部署下一代基于rfid的传感应用以及医疗、环境、能源、军事、国土安全和运输等业务方面产生直接的经济和社会影响。其他福利包括少数民族女研究生参与研究，少数民族研究生通过美国国家科学基金会资助的东北研究生教育和教授联盟（NEAGEP）参与研究。此外，该项目的研究和教学影响了五所学院的学生，其中包括两所女子学院，史密斯学院和芒特霍利奥克学院，由于该联盟的交叉注册政策，这两所学院的学生可以注册马萨诸塞大学教授的课程。课程开发包括通过新的或现有的课程、会议辅导、研讨会和面向高中生的科学博览会演示，让学生接触超低功耗设备的硬件/软件边界的挑战。

This project performs fundamental cross-disciplinary cross-layered research into the design, implementation, and deployment of next-generation harvesting-based RFID-scale sensing technologies. The effort involves research at the CRFID hardware/software interface including energy management, data storage systems, and energy-aware computing to advance knowledge and understanding of zero-power pervasive devices. It addresses several fundamental research challenges including: 1) tradeoffs in energy harvesting, storage and usage that can make RFID sensors more programmable while not compromising energy-efficiency, 2) data storage systems that exploit probabilistic flash writes at low voltages, and that can tolerate frequent interruptions of power, and 3) energy management techniques that expose uncertainty-driven energy management interfaces, and schedule tasks in a harvesting-aware manner. Direct economic and social impacts of this project are expected in the design, development, and deployment of next-generation RFID-based sensing applications and businesses including medical, environmental, energy, military, homeland security, and transportation. Other benefits include involvement of female minority graduate students in research, and involvement of minority graduate students through the NSF-funded Northeast Alliance for Graduate Education and the Professoriate (NEAGEP). Further, the research and teaching from the project impacts students across the Five Colleges, which includes two all-women's colleges, Smith and Mount Holyoke, whose students can enroll in courses taught at UMass because of the consortium's cross-registration policy. Curriculum development includes exposing students to challenges at the hardware/software boundary of ultra-low power devices through new or existing courses, tutorials in conferences, and seminars and demos in science fairs intended for high-schoolers.
