UAV assistance paradigm: State-of-the-art in applications and challenges

Abstract

Unmanned Aerial Vehicles (UAVs) are an emerging technology with the potential to be used in industries and various sectors of human life to provide a wide range of applications and services. During the last decade, there has been a growing focus of research in the UAV's assistance paradigm as a fundamental concept resulting in the constant improvement between different kinds of ground networks and the hovering UAVs in the sky. Recently, the wide availability of embedded wireless interfaces in the communicating entities has allowed the deployment of such a paradigm simpler and easiest. Moreover, due to UAVs' controlled mobility and adjustable altitudes, they can be considered as the most appropriate candidate to enhance the performance and overcome the restrictions of ground networks. This comprehensive survey both studies and summarizes the existing UAV-assisted research, such as routing, data gathering, cellular communications, Internet of Things (IoT) networks, and disaster management that supports existing enabling technologies. Descriptions, classifications, and comparative studies related to different UAV-assisted proposals are presented throughout the paper. By pointing out numerous future challenges, it is expected to simulate research in this emerging and hot research area. To the best of our knowledge, there are many survey papers on the topic from a technology perspective. Nevertheless, this survey can be considered as the first attempt at a comprehensive analysis of different types of existing UAV-assisted networks and describes the state-of-the-art in UAV-assisted research.

Routing and collision avoidance techniques for unmanned aerial vehicles: Analysis, optimal solutions, and future directions

“…Here is a brief description of new opportunities and interesting topics for future research. Many attacks like DoS, eavesdropping, and MITM are some of the most dangerous attacks on UAVs due to the open links between base‐stations and satellites 147 . To avoid such kind of malicious attacks, an optimum quality secure structure for UAVs communication is needed 148 …”

Smart Anti-jamming Mobile Communication for Cloud and Edge-Aided UAV Network

“…It is worth noting that the research on anti-smart jamming is mainly concentrated in wireless networks, and there is almost no related research on UAV networks, except for UAV-aided networks. In [16], the authors systematically reviewed the applications and challenges of UAV-aided networks. In [17], the authors focused on the anti-jamming techniques in VANETs and proposed a hotbooting policy hill climbing (PHC)-based strategy to deal with this kind of jamming.…”

Optimization Methods for Power Allocation and Interference Coordination Simultaneously with MIMO and Full Duplex for Multi-Robot Networks

“…We note that gaps exist between studies focused on power allocation and interference coordination problems in multi-robot networks [17]. These are particularly challenging tasks to address for multi-robot networks because interference is a critical problem influencing the communications between robots, and thereby negatively affecting collaboration between groups of networking robot entities, which becomes more severe when the communication is dominated by line of sight (LoS) channels [18].…”
