Unmanned aerial vehicle-aided networks have been widely recognized by both cellular and internet industry and academia as an emerging technique to enhance current networking infrastructure. The research objective of this project is to design, analyze, and evaluate AirEdge, which is an innovative robust 3D airborne computing and networking system that exploits a swarm of aerial mobile radio access points and edge servers carried or deployed by unmanned aerial vehicles. The unique feature of AirEdge is to enable fast-deployable highly efficient on-demand edge computing and networking services. AirEdge will enable a series of applications in the areas of disaster rescue, public safety, anti-terrorism, battlefield assistance, and mobile entertainment. For example, AirEdge can be rapidly deployed to the area impacted by the disaster and allows first responders to locate and identify injured people using face recognition and provide their corresponding health information for first aids. This project also fosters interdisciplinary research and provides a unique training program for undergraduate and graduate students.This project aims to realize AirEdge through the communication-motion co-design principles for 3D airborne networking and communication-computation co-design principles to enable reliable and energy-efficient airborne edge computing. Toward this end, two fundamental research problems are investigated: 1) how to dynamically establish edge computing networks to enable flexible edge computing and 2) how to integrate dynamic computing resource deployments with the communication network provided by unmanned aerial vehicle (UAVs) to enable low-latency and high-performance edge computing on resource-constrained computing platforms. To address these problems, 1) a new edge-assisted optimal motion control scheme is designed to exploit the abundant computation power of the ground edge server and high-fidelity ray-tracing simulations to perform site-specific Air-to-Ground channel modeling; 2) a new energy-efficient motion planning strategy is developed for the UAV swarm with an objective to simultaneously enhance the area spectral efficiency of the entire serving site and satisfy the time-varying data rate requirements of the edge computing applications; 3) a novel multi-agent actor-critic (MA-AC) reinforcement learning method is developed to realize a more adaptive and robust model-free control scheme under the uncertainties of the deployment environment; 4) a new context-aware adaptive edge computing deployment solution is designed to optimally integrate the airborne edge computing with the airborne communication network; 5) a novel dynamic edge analytics framework is engineered for the airborne communication and computing. The framework leverages approximate computing to mitigate the tradeoff between computation quality, service latency, and energy efficiency in AirEdge.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.

无人机辅助网络已被蜂窝和互联网行业和学术界广泛认可为增强当前网络基础设施的新兴技术。该项目的研究目标是设计、分析和评估 AirEdge，这是一种创新的稳健 3D 机载计算和网络系统，利用无人机携带或部署的大量空中移动无线电接入点和边缘服务器。 AirEdge 的独特功能是支持快速部署、高效的按需边缘计算和网络服务。 AirEdge将在灾难救援、公共安全、反恐、战场援助、移动娱乐等领域实现一系列应用。例如，AirEdge可以快速部署到受灾地区，并允许急救人员使用人脸识别来定位和识别受伤人员，并提供相应的健康信息以进行急救。该项目还促进跨学科研究，并为本科生和研究生提供独特的培训计划。该项目旨在通过3D机载网络的通信-运动协同设计原则和通信-计算协同设计原则来实现AirEdge，以实现可靠和节能-高效的机载边缘计算。为此，研究了两个基本研究问题：1）如何动态建立边缘计算网络以实现灵活的边缘计算；2）如何将动态计算资源部署与无人机（UAV）提供的通信网络集成以实现低-资源受限计算平台上的延迟和高性能边缘计算。为了解决这些问题，1）设计了一种新的边缘辅助最优运动控制方案，利用地面边缘服务器丰富的计算能力和高保真射线追踪模拟来执行特定地点的空对地通道建模； 2）为无人机群开发了一种新的节能运动规划策略，旨在同时提高整个服务站点的区域频谱效率并满足边缘计算应用的时变数据速率要求； 3）开发了一种新颖的多智能体行动批评家（MA-AC）强化学习方法，以在部署环境的不确定性下实现更具适应性和鲁棒性的无模型控制方案； 4）设计了一种新的上下文感知自适应边缘计算部署解决方案，以将机载边缘计算与机载通信网络优化集成； 5) 为机载通信和计算设计了一种新颖的动态边缘分析框架。该框架利用近似计算来减轻 AirEdge 中计算质量、服务延迟和能源效率之间的权衡。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
