摘要

无人驾驶飞行器(UAV)能够进入偏远地区,为通信提供了新的可能性。它们能够根据需求为大量用户提供服务,适应性强是其主要优势。在第六代(6G)网络中,无人机因其成本效益高、部署灵活而备受推崇。然而,无人机的移动性带来了不同类型的干扰问题,导致网络性能和边缘用户的服务质量(QoS)下降。为应对这些挑战,本文介绍了一种基于集群的解决方案,包括三个主要步骤。首先,根据用户请求,使用迷你批量 K-均值聚类在三维(3D)空间部署无人机。 随后,探索重新聚类,以解决聚类内的负载平衡问题。最后,对异常值和边界用户进行分类,以提高边缘用户的服务质量。该模型可有效减少干扰,提高无人机在地面网络中的可靠性。此外,还介绍了一个案例研究,说明无人机如何在地面网络中减少海上通信干扰。数值结果表明,与现有的基线方案相比,拟议方案的吞吐量提高了 33.06%,能耗和时延分别降低了 73.15% 和 9.15%。

Towards an optimal 3-D design and deployment of 6G UAVs for interference mitigation under terrestrial networks

Unmanned aerial vehicles (UAVs) have opened new communication possibilities by being able to access remote areas. Their ability to serve a large number of users based on demand and adaptability is a key strength. In Sixth Generation (6G) networks, UAVs are highly valued for their cost-efficiency and versatile deployment. However, the mobility of UAVs introduces different types of interference issues, resulting in a decrease in network performance and quality of service (QoS) for edge users. To address these challenges, this paper introduces a clustering-based solution involving three main steps. Firstly, UAVs are deployed in three-dimension (3D) space based on user requests using mini-batch K-mean clustering Subsequently, re-clustering is explored to tackle load balancing within clusters. Finally, outliers and boundary users are classified to enhance QoS for edge users. This model effectively reduces interference and boosts UAV reliability in terrestrial networks. Also, a case study is presented to show how UAVs can mitigate interference in maritime communication within terrestrial networks. Numerical results demonstrated that the proposed scheme increases throughput by 33.06% and reduces energy consumption and time delay by 73.15% and 9.15%, respectively, as compared to the existing baseline schemes.
