摘要:

无人机在无数应用中的部署越来越多,这依赖于无缝可靠的无线连接来实现无人机的安全控制和操作。蜂窝技术是为空中飞行的无人机提供基本无线服务的关键推动因素。针对地面使用的现有蜂窝网络可以支持低空无人机用户的初始部署,但存在移动性支持等挑战。在本文中,我们提出了一种新的切换框架,提供高效的移动性支持和可靠的无线连接到由地面蜂窝网络服务的无人机。使用深度强化学习的工具,我们开发了一种深度Q-学习算法来动态优化切换决策,以确保无人机用户的鲁棒连接。仿真结果表明,所提出的框架显着减少了发射机的数量,代价是相对于基线情况的信号强度的小损失,其中无人机总是连接到提供最强接收信号强度的基站。

英文摘要:

The growing deployment of drones in a myriad of applications relies on seamless and reliable wireless connectivity for safe control and operation of drones. Cellular technology is a key enabler for providing essential wireless services to flying drones in the sky. Existing cellular networks targeting terrestrial usage can support the initial deployment of low-altitude drone users, but there are challenges such as mobility support. In this paper, we propose a novel handover framework for providing efficient mobility support and reliable wireless connectivity to drones served by a terrestrial cellular network. Using tools from deep reinforcement learning, we develop a deep Q-learning algorithm to dynamically optimize handover decisions to ensure robust connectivity for drone users. Simulation results show that the proposed framework significantly reduces the number of handovers at the expense of a small loss in signal strength relative to the baseline case where a drone always connect to a base station that provides the strongest received signal strength.
