论文摘要
许多与无人机相关的应用程序（例如无人机视频捕获，无人机交通和安全管理）要求无人机之间的集体通信有效地传播数据或可靠地提供关键信息，从而利用无人机的视线范围来实现地面设备可能无法使用的服务。本文通过轨迹调整研究了高性能但资源有效的移动无人机多播。我们首先分析轨迹调整条件，以确定通过进行简单的计算任务和受控的高架流量，确定多播是否完全涵盖了直线轨迹。然后，我们提出了轨迹调整方案，以提供具有控制的行进距离的新轨迹。最终提出了ETTA算法，以将轨迹调节条件和方案应用于覆盖范围不重叠的转货者之间的无人机。该算法依赖于多播货币，而不是其他过渡转发器，以完全覆盖调整后的轨迹，有助于控制干扰和网络流量负载。我们的NS2仿真结果表明，与其他移动多播相比，ETTA可以在较重的交通负载的多播中实现无人机接收器的保证性能。
Many drone-related applications (e.g., drone-aided video capture, drone traffic and safety management) require group communications between drones to efficiently disseminate data or reliably deliver critical information, making use of the line-of-sight coverage of drones to realise services that ground devices may not be capable of. This paper studies highperformance yet resource-efficient mobile drone multicasting via trajectory adjustment. We first analyse the trajectory adjustment condition to determine whether a straight-line trajectory is fully covered by the multicast or not, by conducting simple computation tasks and with controlled overhead traffic. We then propose the trajectory adjustment scheme to provide a new trajectory with controlled travel distances. The ETTA algorithm is finally presented to apply the trajectory adjustment condition and scheme to a drone transiting between forwarders whose coverage do not overlap. The algorithm relies on multicasting forwarders, instead of additional transition forwarders, to fully cover the adjusted trajectory, helping to control interference and network traffic load. Our NS2 simulation results demonstrate that ETTA, as compared to other mobile multicasts, can achieve guaranteed performance for drone receivers in a multicast with heavier traffic loads.
