CSR: Small: System Support to Build Context Aware Applications at the Edge

智能城市和物联网（IoT）代表着未来几十年的指数级增长、盈利能力和巨大机遇，预计将彻底改变生活。实现这种颠覆性技术巨大潜力的一个关键障碍是，目前还没有任何集成的系统级支持来构建复杂的智慧城市应用或服务。目前的努力主要集中在孤岛上，使用物联网或智慧城市基础设施构建应用程序仍然是一项艰巨的任务。边缘计算技术允许物联网设备产生的数据在更接近其创建位置的地方进行处理，被认为是智慧城市和物联网愿景成功的关键，但该项目寻求解决一些重大挑战。该项目将确定一组核心系统级服务，这些服务需要在边缘构建复杂的上下文感知应用，调查这些服务的设计和实现中的系统和算法挑战，并构建一个整体的中间件框架，以可访问的，良好集成的方式将这些服务公开给边缘应用程序开发人员。该框架的实用性将通过开发三种新型的智能城市和物联网应用程序来展示，这些应用程序代表了未来常见的应用程序类型。总体而言，该项目将加快复杂的上下文感知边缘应用的构建，并为智能城市和物联网领域日益增长的工作做出贡献。该项目将把研究理念融入涉及高中、本科和研究生水平的教育使命中。该框架将提供给学术界和工业界的研究人员，并为边缘计算研究和教育的开源基础设施做出贡献。由于边缘计算在为日常生活构建变革性的上下文感知应用方面具有巨大的潜力，因此拟议的研究将有助于提高生活质量和国家？该奖项反映了NSF的法定使命，并被认为是值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估的支持。

Smart cities and Internet of Things (IoT) represent a domain of exponential growth, profitability, and immense opportunities in the coming decades, and are expected to revolutionize life. A key roadblock in realizing the immense potential of this disruptive technology is that at present there isn't any integrated system level support to build sophisticated smart city applications or services. Current efforts have mostly been in silos and building applications using the IoT or smart city infrastructure remains an arduous task. Edge computing technology, which allows data produced by IoT devices to be processed closer to where it is created is considered crucial for the success of the smart city and IoT visions, but there are some significant challenges that this project seeks to address.The project will identify a set of core system level services needed to build sophisticated context-aware applications at the edge, investigate systems and algorithmic challenges in the design and implementation of these services, and build a holistic middleware framework that exposes these services to the edge application developers in an accessible, well integrated manner. The utility of this framework will be demonstrated by developing three novel smart city and IoT applications that are representatives of the type of applications that will be commonplace in the future. Overall, this project will expedite the construction of sophisticated context-aware edge applications and contribute to the growing body of work on smart city and IoT.The project will integrate research ideas into the educational mission that involves students at high school, undergraduate and graduate levels. The framework will be made available to researchers in academia and industry and contributed to the open source infrastructure for edge computing research and education. As edge computing holds great promise for building transformative context-aware applications for everyday life, the proposed research will contribute to better quality of life and the nation?s economy.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
