Efficient usage of energy in wireless networks represents a major concern in academia and
industry, mainly because of environmental, financial, and quality-of-experience …

The concept of mobile user equipment (UE) relay (UER) has been introduced to support
device-to-device (D2D) communications for enhancing communication reliability. However …

Traditional macrocell networks are experiencing an upsurge of data traffic, and small-cells
are deployed to help offload the traffic from macrocells. Given the massive deployment of …

In this paper, a hybrid radio frequency (RF) and visible light communication (VLC) system is
considered. A hybrid system with multiple VLC access points (APs) and RF APs is designed …

This paper develops a new approach to the modeling and analysis of heterogeneous
cellular networks (HetNets) that accurately incorporates coupling across the locations of …

To guarantee the ubiquitous and fully autonomous Internet connections in our daily life, the
new technical challenges of mobile communications lie on the efficient utilization of resource …

With the proliferation of wireless devices, wireless networks in various forms have become
global information infrastructure and an important part of our daily life, which, at the same …

Traditionally, energy efficiency aspects have been included in the wireless access network
design space only in the context of power control aimed at interference mitigation and for the …

Heterogeneous Network (HetNet), where Small cell Base Stations (SBSs) are densely
deployed to offload traffic from macro Base Stations (BSs), is identified as a key solution to …

In this paper, we analyze and optimize the energy efficiency of downlink cellular networks.
With the aid of tools from stochastic geometry, we introduce a new closed-form analytical …
