Game-Theoretic Approaches for Wireless Communications with Unmanned Aerial Vehicles
Wireless communications with unmanned aerial vehicles (UAVs) offer a
promising solution to provide cost-effective wireless connectivity and extend
coverage. In recent years, the area of wireless communications for UAV system
design and optimization has been receiving enormous attention from the research
community. However, there are still existing challenges that are far from
solved. To cope with those challenges, researchers have been exploring the
applicability of game-theoretic approaches. This paper surveys the existing
game-theoretic solutions and presents a number of novel solutions which are
designed to optimize energy consumption, enhance network coverage, and improve
connectivity in wireless communications with UAVs. We present main game
components and the elements they represent in wireless communications with UAVs
first and then give a classification of the current used game-theoretic
approaches. We identify main problems in wireless communications with UAVs in
which game theory has been used to find solutions. We provide a case to show
the merits of applying game theory in wireless communication with UAVs.
Finally, we discuss shortcomings of the traditional game-theoretic approaches
and propose mean field game (MFG) as an appropriate method for solving novel
technical problems in massive UAVs networks.Comment: 9 pages, 6 figures, This paper was accepted for publication in the

Resource Management and Quality of Service Provisioning in 5G Cellular Networks
With the commercial launch of 5G technologies and fast pace of expansion of
cellular network infrastructure, it is expected that cellular and mobile
networks traffic will exponentially increase. In addition, new services are
expected to spread widely, such as the Internet of Things connected to mobile
networks. This will add additional burden in terms of traffic load. As a
result, some studies suggest that mobile traffic may increase more than 1000
times compared to the amount of traffic that is generated nowadays. This means
that network resources for mobile services must be managed and controlled in a
smart way, because resources are always limited, but the demand for services
and the need for keeping user equipment always connected to mobile networks can
be considered unlimited, leaving gap between huge service demands and available
resources. In order to narrow this gap, major consideration should be given to
the management of network resources to avoid network congestion and performance
degradation during peak hour/s and traffic spikes, and allow access to network
services to more customers when demand is high. On the other hand, guaranteeing
quality of service requirements for the wide range of new services is another
challenge that must be met in 5G networks. In this paper we will review 5G
networks characteristics and specifications, then carry out a survey on
resource management and QoS provisioning to improve and manage resource
utilization in 5G networks.Comment: 21 pages, 8 figures, 3 table
