论文摘要
在本文中，我们考虑了两个跳跃继电系统的多动能部署问题。为了获得更好的网络性能，无人机具有以逼真的辐射模式建模的定向天线。目标是最大化最低用户速率，因此在网络中达到公平性。我们提出了一种迭代算法，以优化啤酒花，无人机轨迹，天线束宽以及基站和继电器的传输功率中的TDMA调度。仿真结果表明，由于优化定向天线辐射模式，吞吐量的改善。此外，我们得出了最佳功率分配，该分配与光束宽度优化相结合的性能得出了更好的性能。
In this paper, we consider the multi-UAV deployment problem for a two-hop relaying system. For a better network performance, UAVs carry directional antennas that are modeled by a realistic radiation pattern. The goal is to maximize the minimum user rates, and therefore achieve fairness in the network. We propose an iterative algorithm to optimize the TDMA scheduling in both hops, UAV trajectories, antenna beamwidths, and transmit power of the base station and relays. Simulation results show the throughput improvement as a result of optimizing the directional antenna radiation patterns. In addition, we derive the optimal power allocation, which combined with the beamwidth optimization yields to a much better performance.
