Time synchronization allows devices in a network to have a common notion of time and thus to operate in a precisely coordinated manner that is essential for the correctness, efficiency, throughput, and security of the entire system. Despite efforts in the past for achieving accurate timing in traditional networks, synchronization remains an open problem for the emerging sustainable wireless networks which are envisioned to play a key role in many future applications such as time-driven smart manufacturing, transportation cyber-physical systems, smart power grids, high-confidence medical systems, etc., due to a wide range of new features and requirements. To support truly sustainable operations, this project will carry out systematic research to revisit the clockwork by carefully identifying constraints from different aspects of such networks. The outcome of this project will constitute a significant advance in the design and development of theoretical foundations and practical algorithms to enable a highly effective synchronization service in sustainable wireless networks. Broader impacts of this project shall be magnified by (i) cultivating collaboration within the computer network community and interdisciplinary cooperation with field experts, (ii) improving curriculum development with hands-on training, (iii) disseminating research results via high-quality publications and open-source websites, (iv) raising interest in science and technology among K-12 students, female, and underrepresented groups through seminars and open house events.This research project will enable reactive, efficient, scalable, and configurable time synchronization for sustainable wireless networks deployed in highly dynamic physical environments. The project will build a sustainable computing hardware prototype with modularized structure that accommodates various solutions for energy harvesting, wireless communication, on-board sensing and processing. New designs will be implemented with a combination of different hardware platforms and the project will deliver reusable system designs, firmware packages, algorithm and protocol libraries to the research community. In addition to academic papers and technical reports, this work is expected to contribute to the system development in broader application communities across multiple disciplines, such as health care and assisted living, urban safety and security, human behavior study, cyber-physical system research, and so forth.

时间同步允许网络中的设备具有通用的时间概念，从而以精确的协调方式运行，这对于整个系统的正确性，效率，吞吐量和安全性至关重要。尽管过去努力在传统网络中实现准确的时机，但同步仍然是新兴的可持续无线网络的开放问题，这些网络设想在许多未来的应用中发挥关键作用，例如时间驱动的智能制造，运输网络物理系统，智能电网，智能电网，高控制医疗系统等，这是由于新功能和需求的范围。为了支持真正的可持续运营，该项目将通过仔细识别此类网络各个方面的约束来进行系统研究以重新审视发条。该项目的结果将构成理论基础和实用算法的设计和开发方面的重大进步，以实现可持续无线网络中高效的同步服务。该项目的更广泛影响应通过（i）在计算机网络社区内培养协作以及与现场专家的跨学科合作，（ii）通过动手培训改善课程开发，（III）通过高质量的出版物和开放源网站（IV）在K-12学生中的开放群体和技术的开放群体（IV）通过高质量出版物和技术的研究来传播研究成果将实现在高度动态的物理环境中部署的可持续无线网络的反应性，高效，可扩展和可配置的时间同步。该项目将通过模块化结构构建可持续的计算硬件原型，该原型可容纳各种解决方案，用于收集能源，无线通信，板载感应和处理。新设计将结合不同的硬件平台的结合，该项目将向研究社区提供可重复使用的系统设计，固件软件包，算法和协议库。除了学术论文和技术报告外，这项工作还有望为跨多个学科的更广泛的应用社区（例如医疗保健和辅助生活，城市安全与保障，人类行为研究，网络物理系统研究等）做出贡献。
