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共同的时间概念，从而以精确协调的方式操作，这对于整个系统的正确性、效率、吞吐量和安全性至关重要。尽管过去在传统网络中努力实现精确定时，但同步对于新兴的可持续无线网络仍然是一个开放的问题，这些无线网络被设想在许多未来应用中发挥关键作用，例如时间驱动的智能制造、交通网络物理系统、智能电网、高置信度医疗系统等。由于广泛的新特征和要求。为了支持真正的可持续运营，该项目将进行系统研究，通过仔细确定此类网络不同方面的限制因素，重新审视钟表机构。该项目的成果将在理论基础和实用算法的设计和开发方面取得重大进展，从而在可持续的无线网络中实现高效的同步服务。本项目的更广泛影响将通过以下方式扩大：（i）培养计算机网络社区内的合作和与领域专家的跨学科合作，（ii）通过实践培训改进课程开发，（iii）通过高质量出版物和开源网站传播研究成果，（iv）提高K-12学生对科学和技术的兴趣，女性，该研究项目将为部署在高度动态物理环境中的可持续无线网络实现反应式、高效、可扩展和可配置的时间同步。该项目将建立一个具有模块化结构的可持续计算硬件原型，可容纳用于能量收集，无线通信，车载传感和处理的各种解决方案。新的设计将结合不同的硬件平台实施，该项目将向研究界提供可重复使用的系统设计、固件包、算法和协议库。除了学术论文和技术报告，这项工作预计将有助于系统开发在更广泛的应用社区跨多个学科，如医疗保健和辅助生活，城市安全和保障，人类行为研究，网络物理系统研究，等等。
