CPS: Medium: A Cross-Layer Approach to Taming Cyber-Physical Uncertainties in Vehicular Wireless Networking and Platoon Control

该项目提出了一个跨层框架，其中车辆无线网络和排控制相互作用，以驯服网络物理不确定性。队列控制根据无线网络的实时容量区域和车辆运动的物理过程，选择控制策略以及相应的无线数据传输的时效性和吞吐量要求，优化控制性能。无线网络根据排控的要求，控制同信道干扰，适应网络物理的不确定性，保证单跳和多跳广播的时效性和吞吐量。为了主动解决车辆移动性对无线广播的影响，无线网络还利用队列控制对车辆运动预测的输入。在实现跨层框架时，无线调度确保了在存在网络物理不确定性的情况下灵活、可预测的干扰控制。如果成功，该项目将为无线车辆信息物理网络控制提供一个通用而严格的框架，从而实现安全、高效和清洁的运输。驯服网络物理不确定性的原理和技术将为无线网络传感和控制的其他应用领域（如无人机和智能电网）提供见解。该计划还将通过多层次、多组件的教育活动，发展无线网络物理系统的综合研究和教育。

This project proposes a cross-layer framework in which vehicular wireless networking and platoon control interact with each other to tame cyber-physical uncertainties. Based on the real-time capacity region of wireless networking and the physical process of vehicle movements, platoon control selects its control strategies and the corresponding requirements on the timeliness and throughput of wireless data delivery to optimize control performance. Based on the requirements from platoon control, wireless networking controls co-channel interference and adapts to cyber-physical uncertainties to ensure the timeliness and throughput of single-hop as well as multi-hop broadcast. For proactively addressing the impact of vehicle mobility on wireless broadcast, wireless networking also leverages input from platoon control on vehicle movement prediction. In realizing the cross-layer framework, wireless scheduling ensures agile, predictable interference control in the presence of cyber-physical uncertainties. If successful, this project will lead to a general and rigorous framework for wireless vehicular cyber-physical network control that will enable safe, efficient, and clean transportation. The principles and techniques for taming cyber-physical uncertainties will provide insight into other application domains of wireless networked sensing and control such as unmanned aerial vehicles and smart power grids. This project will also develop integrative research and education on wireless cyber-physical systems through multi-level, multi-component educational activities.
