论文摘要
无人驾驶飞机（UAV）已成功用于在应用程序中提供通信服务，例如在偏远地区扩大5G蜂窝网络的覆盖范围，紧急情况以及提高密集的用户群体地区的服务质量。尽管在文献中提出了优化的放置解决方案，以确保用户的服务质量（QoS），但它们在高度移动，自主和多样化的网络方案中可能并不理想。本文提出了一个主动且具有弹性的框架，用于对无人机小单元的分布式和动态编排，以在网络中提供QoS分化。无人机位置是针对最终用户位置和服务需求量身定制的，同时确保无人机保持局部回程连接。仿真实验表明，在物理位置可以实现服务差异化的情况下，开发的框架会导致无人机的稳定配置，该配置满足了90％的用户QoS要求。
Unmanned aerial vehicles (UAVs) are being successfully used to deliver communication services in applications such as extending the coverage of 5G cellular networks in remote areas, emergency situations, and enhancing the service quality in regions of dense user populations. While optimized placement solutions have been proposed in literature for ensuring quality of service (QoS) of users, they may not be ideal in highly mobile, autonomous, and diverse network scenarios. This paper proposes a proactive and resilient framework for distributed and dynamic orchestration of UAV small cells to provide QoS differentiation in the network. The UAV locations are tailored to end-user locations and service needs while ensuring that UAVs maintain localized backhaul connectivity. Simulation experiments show that under scenarios where physical placement can achieve service differentiation, the developed framework leads to a stable configurations of UAVs satisfying above 90% of user QoS requirements.
