在一个区域内部署大量无人机会导致无线电频率（RF）频谱过度拥挤，需要无人机协调频率选择和移动性以防止数据丢失。目前在多无人机系统干扰协调方面的工作通过使用轨迹和功率控制或信道分配来减少干扰，但不是两者兼而有之。我们提出了一种新的控制器，选择通道，创建轨迹，并控制每个无人机的发射功率，以增加多无人机系统的网络容量。结果表明，所提出的控制器产生27%的最先进的无人机频率复用算法的国家增加的网络容量，152%的最先进的无人机轨迹和功率控制器的国家增加的网络容量，和135%的速度更快的整体控制。
Deploying large numbers of unmanned aerial vehicles (UAVs) within a region can result in an overcrowded radio frequency (RF) spectrum, requiring UAVs to coordinate frequency selection and mobility to prevent data loss. Current work in interference coordination for multi-UAV systems reduces interference through the use of either trajectory and power control or channel assignments, but not both. We propose a novel controller which selects channels, creates trajectories, and controls transmit power for each UAV to increase the networking capacity of a multi-UAV system. Results show that the proposed controller yields 27% increased network capacity over state of the art UAV frequency reuse algorithms, 152% increased network capacity over state of the art UAV trajectory and power controllers, and 135% faster control overall.
