在5G网络中使用无人机进行短期和长期小区中断补偿

摘要:

无人机(UAV)的使用由于其许多用途和优点(诸如快速部署和多用途功能)而在无线网络中引起了兴趣。这就是为什么无人机的广泛部署有可能被整合到即将到来的5G标准中。它们可以用作飞行基站,可以在地面基站(GBS)故障的情况下部署。这种失败可以是短期的,也可以是长期的。基于故障的类型和持续时间,我们提出了一个框架,使用无人机或直升机,以减轻GBS故障。我们提出的短期和长期小区中断补偿框架旨在减轻5G网络中任何GBS故障的影响。在我们的框架内,停电补偿是在天空BS(无人机)的帮助下完成的。一个优化问题,制定联合最小化的无人机的通信功率和最大化的最小速率的用户设备(UE)受故障影响。此外,无人机的最佳位置被确定。仿真结果表明,该框架保证了最低的服务质量为每个UE,除了最小化无人机的消耗能量。

英文摘要:

The use of Unmanned Aerial Vehicles (UAVs) has gained interest in wireless networks for its many uses and advantages such as rapid deployment and multi-purpose functionality. This is why wide deployment of UAVs has the potential to be integrated in the upcoming 5G standard. They can be used as flying base-stations, which can be deployed in case of ground Base-Stations (GBSs) failures. Such failures can be short-term or long-term. Based on the type and duration of the failure, we propose a framework that uses drones or helikites to mitigate GBS failures. Our proposed short-term and long-term cell outage compensation framework aims to mitigate the effect of the failure of any GBS in 5G networks. Within our framework, outage compensation is done with the assistance of sky BSs (UAVs). An optimization problem is formulated to jointly minimize communication power of the UAVs and maximize the minimum rates of the Users' Equipment (UEs) affected by the failure. Also, the optimal placement of the UAVs is determined. Simulation results show that the proposed framework guarantees the minimum quality of service for each UE in addition to minimizing the UAVs' consumed energy.
