To reduce the average file delivery time under limited backhaul bandwidth and cache
storage, we propose a fractional dynamic caching scheme, that coordinates the utilization of …

In this paper, the joint beamforming design for max-min fair simultaneous wireless
information and power transfer (SWIPT) is investigated in a green cloud radio access …

Cellular communication networks are plagued with redundant capacity, which results in low
infrastructure utilization and low cost-effectiveness of network capital investments. This …

This paper investigates the multi-relay non-orthogonal multiple access (NOMA) networks
with cache-enabled users, in which the source transmits superimposed signals to two users …

Multimedia content, especially videos, is expected to dominate data traffic in next-generation
mobile networks. Caching popular content at the network edge, namely content helpers …

We study the problem of proactively pushing contents into a finite capacity cache memory of
a user equipment in order to reduce the long-term average energy consumption in a …

Caching has attracted much attention recently because it holds the promise of scaling the
service capability of radio access networks (RANs). We envision that caching will ultimately …

The integration of ad hoc device-to-device (D2D) communications and open-access small
cells can result in a networking paradigm called hybrid the ad hoc network, which is …

The moving small-cell (mSC) is one of solutions to accommodate traffic of the moving users
cost-effectively. Due to cache storage in mSC, an mSC can directly send its data for its …

This thesis explores one of the key enablers of 5G wireless networks leveraging small cell
network deployments, namely proactive caching. Endowed with predictive capabilities and …
