Relying on offloading computation tasks to the network edge, ultra dense networks (UDNs)
are capable of providing delay-aware service to nearby users. Meanwhile, software defined …

To reduce the interference among small cells of Ultra-Dense Networks (UDN), an improved
Clustering-Assisted Resource Allocation (CARA) scheme is proposed in this paper. The …

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 …

To meet the demand of various high-speed data rate services as well as serving an
exponential increment of mobile devices, millimeter-Wave (mmWave) communication in …

The development of wireless networks can be characterized by both the increased number
of deployed network nodes as well as their greater heterogeneity. As a consequence, the …

Unmanned aerial vehicles (UAVs) are expected to provide data service to users as aerial
base stations, as gateways to collect the data from various sensors, and as sensor-mounted …

One of the recent approaches for improving capacity of future wireless network is to increase
the density of nodes by deployment of short-range base stations called small cells. When the …

Ultra-dense networks can further improve the spectrum efficiency (SE) and the energy
efficiency (EE). However, the interference avoidance and the green design are becoming …
