摘要:

无人机(UAV)处于尖端技术的最前沿,在广泛的学科领域具有无与伦比的开拓性应用潜力。特别是在认知无线电(CR)领域,这是新的5G电信技术实施的关键方面。无人机和CR之间的集成巩固了无人机在CR支持的非常有前途的物联网(IoT)技术核心的能力。与地面无线网络相比,高度动态的网络拓扑、弱网络通信链路、可靠的视距(LOS)通信链路以及轨道或飞行路径是UAV通信的典型特征。然而,该系统的实现受到几个严峻挑战的限制,例如能量效率、电池功率限制、频谱切换、传播信道建模、路由协议、安全策略和延迟挫折。在本文中,我们考虑了无人机在各种CR应用中所面临的能源短缺的影响。我们还分析了能源短缺对基于通信的应用程序的影响,并提出了电池限制的一般问题。最后,我们给出了通信领域和基于电池的研究人员提出的最新解决方案之间的概述和比较,并根据最新技术水平考虑可能的未来方向,例如新的图形信号处理(GSP)和机器学习(ML)。

英文摘要:

Unmanned Aerial Vehicles (UAVs), which are at the forefront of cutting-edge technology, have unmatched potential for pioneering applications in a wide range of disciplines. In particular, in the field of cognitive radio (CR), which is a key aspect in the implementation of the new 5G telecommunication technology. The integration between the drone and CR consolidates the drone's capabilities at the heart of the remarkably promising Internet-of-Things (IoT) technology supported by CR. The highly dynamic network topologies, weakly networked communication links, reliable line-of-sight (LOS) communication links, and orbital or flight paths are characteristic features of UAV communication compared to terrestrial wireless networks. Nevertheless, the implementation of this system is constrained by several severe challenges, such as energy efficiency, battery power limitation, spectrum handover, propagation channel modeling, routing protocols, security policy, and delay setbacks. In this paper, we consider the impact of energy scarcity faced by the UAV in various CR applications. We also analyze the impact of energy scarcity on communication-based applications and present the general problem of battery limitation. Finally, we give an overview and comparison between recent solutions proposed by researchers both in the field of communication and based on batteries and consider possible future directions according to the state of the art, such as novel Graph Signal Processing (GSP) and machine learning (ML).
