EAGER: Hardware and Software Architecture for Wireless Sensing Systems Under Dynamic Load and Energy Availability

物联网与无处不在的计算视觉相呼应，捕捉了一个由智能物体、结构和材料组成的深度连接的世界。在这一愿景中，使用短暂能源的资源受限设备将发挥重要作用。该项目实现了一种新型嵌入式系统，该系统在动态负载和采集条件下具有固有的鲁棒性和适应性，这些条件将在新兴的物联网中普遍存在。该项目正在设计和评估基本的硬件和软件扩展，这些扩展与现有方法完全不同，具有潜在的变革性结果。与此同时，该项目为本科生和研究生提供研究培训，有助于扩大参与范围，并推动建立检测灌溉系统地下泄漏的新系统。该技术计划包括四个相关的重点：(1)该团队正在探索一种基于联合储能概念的新的能量收集和放电架构。新架构支持充电和放电优先级的动态控制，以及每个组件的实值输入。S电荷态。(2)该团队正在探索新的操作系统服务，用于管理充放电优先级，以及查询每个组件的当前充电状态。(3)该团队正在探索基于充电状态信息计算组件使用寿命的新方法。(4)最后，该小组正在建立一个可操作的测试平台，以评估所得技术的效用，利用正在进行的住宅灌溉泄漏检测工作。

The Internet of Things echoes the ubiquitous computing vision, capturing a deeply connected world populated by intelligent objects, structures, and materials. Resource-constrained devices that operate from ephemeral energy sources have a prominent role to play in this vision. This project is enabling a new class of embedded system that is inherently robust and adaptive in the presence of dynamic load and harvesting conditions - conditions that will be pervasive in the emerging Internet of Things. The project is designing and evaluating fundamental hardware and software extensions that are radically different from existing approaches, with potentially transformative results. At the same time, the project is providing research training for undergraduate and graduate students, contributing to broadening participation, and driving progress toward a new system for detecting underground leaks in irrigation systems.The technical plan involves four related thrusts: (1) The team is exploring a new energy harvesting and discharge architecture based on the concept of federated energy storage. The new architecture enables dynamic control of charge and discharge priorities, as well as real-valued inputs regarding each component?s charge state. (2) The team is exploring new operating system services for managing charge and discharge priorities, as well as for querying the current charge state of each component. (3) The team is exploring new approaches to calculating component service life based on state-of-charge information. (4) Finally, the team is building an operational testbed for evaluating the utility of the resulting techniques, leveraging ongoing work in the detection of residential irrigation leaks.
