Space-air-ground integrated networks for ubiquitous connectivity and mobile computing experience

在过去几年中，无线通信和移动的计算技术的发展取得了巨大的成功。值得注意的例子包括5G无线蜂窝网络的推出和部署，无人机（UAV）通信，密集的低地球轨道（LEO）卫星以及全球许多国家的云/边缘计算技术。然而，现有的无线网络仍然远远不能在整个地球上提供真正无处不在和沉浸式的连接和计算体验，并有效地支持许多新兴的民用和军用应用和用例，例如无线虚拟/增强现实，全息通信/远程呈现和实时多感官通信。因此，学术界和工业界对开发使能技术以有效管理、运行和协调空-空-地一体化网络不同网络部分以应对这些挑战非常感兴趣。这也是本研究计划的重点。 这项研究计划的长期目标是为SAGIN开发支持技术，提供无处不在的无线连接和移动的计算体验。为此，该研究计划将致力于以下短期研究目标：1）无人机布局/轨迹控制和无线回程无人机辅助网络的资源管理; 2）利用多输入多输出（MIMO）通信和智能反射面（IRS）技术的地面-空中网络部分的先进无线电资源分配和网络控制; 3）用于SAGIN的地面、空中和空间网络段的有效协调的资源管理和路由;以及4）用于SAGIN的资源分配、计算卸载和网络管理。这项研究计划将有助于塑造未来的宽带和无处不在的通信和移动的计算生态系统，以有效地支持民用和军用应用/服务部门。因此，它将在技术和经济方面产生重大贡献和影响，有助于保持加拿大在国际格局中的领导地位，并有助于促进加拿大的安全。特别是，在这项研究计划中进行的研究将导致创新的无线，卫星通信和计算技术，以实现许多新兴的应用，并提供无处不在的通信和计算服务。此外，拟议的研究将能够培养高素质的人才（HQP）在寻求和关键技术领域。

Tremendous success in the development of wireless communications and mobile computing technologies has been achieved in the last few years. Notable examples include the rollout and deployment of 5G wireless cellular networks, unmanned aerial vehicle (UAV) communications, dense low earth orbit (LEO) satellites, and cloud/edge computing technologies in many countries around the world. However, existing wireless networks are still far from delivering truly ubiquitous and immersive connectivity and computing experience across the entire planet and efficiently supporting many emerging civilian and military applications and use cases such as wireless virtual/augmented reality, holographic communications/telepresence, and real-time multi-sensory communications. Development of enabling technologies for effective resource management, operation, and coordination of different network segments of the space-air-ground integrated network (SAGIN) to address these challenges has therefore received great interests from academia and industry. This is also the focus of this research program. The long-term objective of this research program is to develop enabling technologies for the SAGIN that provide ubiquitous wireless connectivity and mobile computing experience. Toward this end, the research program will address the following short-term research objectives: 1) UAV placement/trajectory control and resource management for UAV-assisted networks with wireless backhauls; 2) Advanced radio resource allocation and network control for the terrestrial-aerial network segments leveraging multiple input multiple output (MIMO) communications, and intelligent reflecting surfaces (IRS) technologies; 3) Resource management and routing for efficient coordination of the terrestrial, aerial, and spatial network segments of the SAGIN; and 4) Resource allocation, computation offloading, and network management for the SAGIN. This research program will contribute to shape the future broadband and ubiquitous communication and mobile computing eco-system to efficiently enable and support both civilian and military application/service sectors. Therefore, it will have significant contributions and impacts in both technical and economic viewpoints and it will help maintain the leadership of Canada in the international landscape and contribute to advance Canadian security. In particular, the research conducted in this research program will lead to innovative wireless, satellite communications, and computing technologies to realize many emerging applications and provide ubiquitous communications and computing services. In addition, the proposed research will enable to train Highly Qualified Personnel (HQP) in the well-sought and critical technology domains.
