In this paper, we consider a single cell downlink non-orthogonal multiple access (NOMA)
network and aim at maximizing the energy efficiency. The energy-efficient resource …

Recently, the mobile wireless communication has seen explosive growth in data traffic which
might not be supported by the current Fourth Generation (4G) networks. The Fifth Generation …

Classic network utility maximization (NUM) problems are usually solved assuming all
information is available, implying that information not locally available is always truthfully …

This paper focus on the two-tier downlink heterogeneous networks (HetNets) with non-
orthogonal multiple access (NOMA). The aim is to jointly optimize user scheduling and …

With the large expected demand of wireless communication, Device-to-Device (D2D)
communication has been proposed as a promising technology to enhance network …

A cellular unmanned-aerial-vehicle (UAV)-enabled system is studied in this research, where
multiple UAVs work cooperatively to upload the collected sensory data to the base station …

Recently, there has been a growing trend toward applying game theory (GT) to various
engineering fields in order to solve optimization problems with different competing …

Structureless communications such as Device-to-Device (D2D) relaying are undeniably of
paramount importance to improving the performance of today's mobile networks. Such a …

This paper studies the cognitive wireless powered device-to-device (D2D) communication
underlaying a cellular network, where there are two types of communications, including peer …

This paper firstly analyzes the network topology model of the UAV cluster network and
wireless 5G communication channel model by modeling and briefly analyzes the idea of …
