论文摘要
无人驾驶汽车（UAV）是携带移动基站以快速为地面用户设置通信服务的便捷选择。与地面网络不同，无人机没有光纤后途连接，除非它们被束缚在地面上，从而限制了它们的活动能力。在没有背面的情况下，例如在偏远地区，紧急情况或战场上，除了覆盖地面用户以创建本地网络外，还需要确保无人机之间的连通性。本文为基于无人机形成的控制提供了一种分布式和动态的方法，用于覆盖和空间分散用户的连接。我们使用羊群动力学作为即时构造无人机形成的指南。仿真结果表明，如果有足够的航空基站可用，则提出的方法会导致无人机的紧密联系网络，该网络能够同时提供回程和领先的网络。该方法可以进一步扩展，以创建多层外网络以适应大规模应用程序。
Unmanned aerial vehicles (UAVs) are a convenient choice for carrying mobile base stations to rapidly setup communication services for ground users. Unlike terrestrial networks, UAVs do not have fiber optic back-haul connectivity except when they are tethered to the ground, which restricts their mobility. In the absence of back-haul, e.g., in remote areas, emergency situations, or in battlefields, there is a need to ensure connectivity among UAVs in addition to coverage of ground users for creating local area networks. This paper provides a distributed and dynamic approach for UAV formation-based control for coverage and connectivity of spatially dispersed users. We use flocking dynamics as a guide to constructing tailored formations of UAVs on the fly. Simulation results demonstrate that if sufficient aerial base stations are available, the proposed approach results in a strongly connected network of UAVs that is able to provide both a backhaul and fronthaul network. The approach can be further extended to create multi-tier extra-terrestrial networks to cater for large-scale applications.
