Power Control in UAV-Supported Ultra Dense Networks: Communications, Caching, and Energy Transfer

摘要

By means of network densification, ultra dense networks (UDNs) canefficiently broaden the network coverage and enhance the system throughput. Inparallel, unmanned aerial vehicles (UAVs) communications and networking haveattracted increasing attention recently due to their high agility and numerousapplications. In this article, we present a vision of UAV-supported UDNs.Firstly, we present four representative scenarios to show the broadapplications of UAV-supported UDNs in communications, caching and energytransfer. Then, we highlight the efficient power control in UAV-supported UDNsby discussing the main design considerations and methods in a comprehensivemanner. Furthermore, we demonstrate the performance superiority ofUAV-supported UDNs via case study simulations, compared to traditional fixedinfrastructure based networks. In addition, we discuss the dominating technicalchallenges and open issues ahead.
