论文摘要
用作飞行基站（Flybss）的无人机（UAVS）的使用被认为是提高移动网络性能的有效工具。然而，这种潜在的改进需要有效的蝇泡定位。在本文中，我们最大限度地提高了Flybs提供的移动互联网设备（IOTD）的总和下行链路容量，同时保证了每个设备所需的最低所需容量。为此，我们提出了一种几何方法，允许随着时间的流逝，随着时间的流逝，可以得出飞行的3D位置，并确定IOTD的传输功率分配。该问题是在Flybs的传播和推进功耗以及飞行速度的实用限制下制定和解决的。所提出的解决方案的复杂性低，与最先进的作品相比，总和容量增加了15％-46％。
The use of unmanned aerial vehicles (UAVs) acting as flying base stations (FlyBSs) is considered as an effective tool to improve performance of the mobile networks. Nevertheless, such potential improvement requires an efficient positioning of the FlyBS. In this paper, we maximize the sum downlink capacity of the mobile Internet of Things devices (IoTD) served by the FlyBSs while a minimum required capacity to every device is guaranteed. To this end, we propose a geometrical approach allowing to derive the 3D positions of the FlyBS over time as the IoTDs move and we determine the transmission power allocation for the IoTDs. The problem is formulated and solved under practical constraints on the FlyBS's transmission and propulsion power consumption as well as on flying speed. The proposed solution is of a low complexity and increases the sum capacity by 15%-46% comparing to state-of-the-art works.
