Unmanned Aerial Vehicle With Underlaid Device-to-Device Communications: Performance and Tradeoffs
TLDR
Simulation and analytical results show that, depending on the density of D2D users, the optimal values for the UAV altitude, which lead to the maximum system sum-rate and coverage probability, exist. Expand
A Vision of 6G Wireless Systems: Applications, Trends, Technologies, and Open Research Problems
TLDR
This article identifies the primary drivers of 6G systems, in terms of applications and accompanying technological trends, and identifies the enabling technologies for the introduced 6G services and outlines a comprehensive research agenda that leverages those technologies. Expand
A Tutorial on UAVs for Wireless Networks: Applications, Challenges, and Open Problems
TLDR
This tutorial provides key guidelines on how to analyze, optimize, and design UAV-based wireless communication systems on the basis of 3D deployment, performance analysis, channel modeling, and energy efficiency. Expand
Cache-enabled small cell networks: modeling and tradeoffs
TLDR
This work considers a network model where small base stations have caching capabilities as a means to alleviate the backhaul load and satisfy users’ demand, and derives closed-form expressions for the outage probability and the average delivery rate as a function of the signal-to-interference-plus-noise ratio (SINR), SBS density, target file bitrate, storage size, file length, and file popularity.

Mobile Unmanned Aerial Vehicles (UAVs) for Energy-Efficient Internet of Things Communications
TLDR
To enable reliable uplink communications for the IoT devices with a minimum total transmit power, a novel framework is proposed for jointly optimizing the 3D placement and the mobility of the UAVs, device-UAV association, and uplink power control. Expand
Ultrareliable and Low-Latency Wireless Communication: Tail, Risk, and Scale
TLDR
A principled and scalable framework which takes into account delay, reliability, packet size, network architecture and topology, and decision-making under uncertainty is sorely lacking and is a first step to filling this void. Expand
Efficient Deployment of Multiple Unmanned Aerial Vehicles for Optimal Wireless Coverage
TLDR
The results show that, in order to mitigate interference, the altitude of the UAVs must be properly adjusted based on the beamwidth of the directional antenna as well as coverage requirements. Expand
Matching theory for future wireless networks: fundamentals and applications
TLDR
This first comprehensive tutorial on the use of matching theory, a Nobel Prize winning framework, for resource management in wireless networks is developed and results show how matching theory can effectively improve the performance of resource allocation in all three applications discussed. Expand
