Edge computing is an emerging paradigm that extends cloud computing by allocating a range of (edge) servers at or near the user to provide necessary networking, storage, and computing services. Cyber-physical systems (CPS) connect physical devices to the Internet and to each other. This research explores the marriage between edge computing and CPS, namely edge-based CPS. It has attracted a tremendous amount of attention from both academia and industry because it is expected to fundamentally change the way people interact with engineered systems. One essential element –the study of fault-tolerant distributed primitives– is still missing in the literature. This research is focused on distributed consensus primitives that allow a collection of nodes to work as a coherent entity in the presence of various failures and cyberattacks. Concretely, there are three interrelated tasks: (i) identifying fundamental properties, limitations, and trade-offs in the context of edge-based CPS; (ii) designing algorithms that automatically adapt under changing conditions and varying cyberattacks to maintain good performance; and (iii) designing and implementing a realistic simulator to study performance under practical scenarios. The expected outcomes will enable efficient and fault-tolerant services for edge-based CPS, allowing more innovation in CPS applications. This research is expected to advance the state of knowledge by identifying a set of principles, fault-tolerance tools, and analyses for designing distributed fault-tolerant primitives. The work will emphasize models and primitives that allow for practical implementation, with plans for realistic demonstrations of their fault-tolerance and performance advantages. Edge computing and CPS are expected to be key components of next-generation infrastructure, so making edge-based CPS fault-tolerant can yield large-scale benefits. Conversely, missed opportunities for improvements caused by a lack of foundational understanding could have significant performance and fault-tolerance consequences. This research helps address these issues by identifying trade-offs and limitations. The proposed research also plans to develop new pedagogical material on distributed systems that the PI plans to teach, both through courses at Boston College and in online tutorials made available to the public. In addition, the research and outreach work will benefit society by providing principles to help industry and academia design fault-tolerant primitives for edge-based CPS; increasing partnerships between academia and industry; involving women, persons with disabilities, and underrepresented groups in STEM; and increasing public scientific literacy and public engagement with science and technology.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.

边缘计算是一种新兴范式，它通过分配用户或附近的一系列（边缘）服务器来提供必要的网络，存储和计算服务来扩展云计算。网络物理系统（CPS）将物理设备连接到互联网，彼此之间。这项研究探讨了边缘计算与CP之间的婚姻，即基于边缘的CP。它引起了学术界和行业的极大关注，因为它有望从根本上改变人们与工程系统互动的方式。文献中仍然缺少一个必不可少的元素 - 对耐断层分布的原始物的研究。这项研究的重点是分布式共识基础，这些共识原始人可以在存在各种故障和网络攻击的情况下作为一个连贯的实体发挥作用。具体而言，有三个相互关联的任务：（i）在基于边缘的CP的背景下识别基本属性，限制和权衡； （ii）设计算法在不断变化的条件下自动调整并改变网络攻击以保持良好的性能； （iii）设计和实施现实的模拟器以在实际情况下研究性能。预期的结果将为基于边缘的CPS提供高效且容忍故障的服务，从而在CPS应用程序中提供更多创新。预计这项研究将通过识别一组原理，容忍缺陷的工具以及设计分布式耐故障基原始人的分析来推动知识的状态。这项工作将强调允许实施实际实施的模型和原始人，并计划对其容忍度和性能优势进行现实的展示。 Edge Computing和CP有望是下一代基础架构的关键组成部分，因此使基于边缘的CPS耐受耐受剂可以产生大规模的好处。相反，由于缺乏基础理解而导致的改进机会可能会带来重大的表现和容忍度的后果。这项研究通过确定权衡和局限性来帮助解决这些问题。拟议的研究还计划在PI计划通过波士顿学院的课程和在线教程中开发的分布式系统上开发新的教学材料。此外，研究和外展工作将通过提供原则来帮助基于边缘的CP的行业和学术界设计容忍的原始原则来使社会受益；增加学术界与行业之间的伙伴关系；涉及妇女，残疾人和STEM中代表性不足的群体；该奖项反映了NSF的法定任务，并通过基金会的知识分子优点和更广泛的影响标准，这一奖项反映了NSF的法定任务，并被认为是珍贵的支持。
