Meeting citizens' requirements economically and efficiently is the most important objective of
Smart Cities. As a matter of fact, they are considered a key concept both for future Internet …

This article provides an overview on research in energy-efficient wireless networks during
the past decade and discusses its potential applications toward the fifth generation cellular …

What would a cellular network designed for maximal energy efficiency look like? To answer
this fundamental question, tools from stochastic geometry are used in this paper to model …

Considering both non-line-of-sight (NLoS) and line-of-sight (LoS) transmissions, the
transitional behaviors from noise-limited regime to dense interference-limited regime have …

We characterize a two tier heterogeneous network, consisting of classical sub-6 GHz macro
cells, and multi radio access technology (RAT) small cells able to operate in sub-6 GHz and …

In this paper, we present a new and significant theoretical discovery. If the absolute height
difference between base station (BS) antenna and user equipment (UE) antenna is larger …

Heterogeneous small cell networks, or Het-SNets, are considered as a standard part of
future mobile networks in which multiple lowpower low-cost user deployed base stations …

The densification and expansion of wireless networks pose new challenges on energy
efficiency. With a drastic increase of infrastructure nodes (eg ultradense deployment of small …

Conventional cellular wireless networks were designed with the purpose of providing high
throughput for the user and high capacity for the service provider, without any provisions of …

Traditional ultra-dense wireless networks are recommended as a complement for cellular
networks and are deployed in partial areas, such as hotspot and indoor scenarios. Based on …
