一种有效的无人机无缝多播过渡算法

An Efficient Transition Algorithm For Seamless Drone Multicasting

Wanqing Tu

摘要:

许多与无人机相关的应用(例如,无人机辅助视频捕获、无人机交通和安全管理)需要无人机之间的群组通信,以有效地传播数据或可靠地传递关键信息,利用无人机的视线覆盖范围来实现地面设备可能无法实现的服务。本文研究了高性能但资源有效的移动无人机多播通过轨迹调整。我们首先分析的轨迹调整条件,以确定是否直线轨迹是完全覆盖的组播或没有,通过进行简单的计算任务和控制开销的流量。然后,我们提出了轨迹调整方案,以提供一个新的轨迹与控制旅行距离。最后,提出了ETTA算法,将轨迹调整条件和方案应用于无人机在覆盖范围不重叠的转发器之间过渡。该算法依赖于多播转发器,而不是额外的过渡转发器,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,ETTA,相比其他移动多播,可以实现保证性能的无人机接收机在多播较重的流量负载。

英文摘要:

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.
