Abstract

Unmanned aerial vehicles (UAVs) have been demonstrated immense potentials to enhance communication systems tailored to the unique characteristics by optimizing the placement and mobility. However, most of the studies focus on UAV-enabled wireless communications such as aerial base stations and relays. The UAV swarm communication is also an important scenario but challenging due to the limited spectrum resources and serious interference among UAV swarms. This letter proposes a topology optimization method for UAV swarm communication, where each UAV transmits data to a collection center directly or via other UAVs while considering malicious jamming. The proposed method jointly designs the information transmission path of all UAVs and transmission power to simultaneously maximize the minimum communication network capacity among all UAVs. A power control algorithm is also proposed to derive the network capacity under a given information transmission path. Simulation results indicate that the proposed topology optimization method increases network capacity compared with other benchmark algorithms.
具有干扰的无人机群通信拓扑优化
无人驾驶飞行器(uav)已经被证明具有巨大的潜力,可以通过优化放置和机动性来增强通信系统的独特特性。然而,大多数研究集中在无人机支持的无线通信,如空中基站和中继。无人机群通信也是一种重要的通信场景,但由于频谱资源有限和无人机群间干扰严重,因此具有挑战性。本文提出了一种无人机群通信的拓扑优化方法,在考虑恶意干扰的情况下,每架无人机直接或通过其他无人机向收集中心传输数据。该方法通过联合设计各无人机的信息传输路径和传输功率,同时实现各无人机间通信网络容量最小的最大化。同时,提出了一种功率控制算法来计算给定信息传输路径下的网络容量。仿真结果表明,与其他基准算法相比,所提出的拓扑优化方法提高了网络容量。

期刊介绍: The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
