Future mobile networks have to be densified by employing small cells to handle the upsurge
in traffic load. Although the amount of energy each small cell consumes is low, the total …

Base station operation consumes a lot of energy, a considerable amount of which can be
saved by switching off base stations during low user demand (for example, at night). Base …

Abstract 5G communication technologies are expected to provide high rate and low delay
services. To meet the requirements, more base stations (BS), including macrocell BS …

The increasing demand for high bandwidth in cellular wireless networks led to a dramatic
increase in the number of deployed LTE femtocell base stations (FBS) in recent years. While …

With enormous growth in the telecommunication industry, energy efficiency has become a
critical issue. Base stations and the core network account for a large amount of energy …

In this paper, we adopt stochastic geometry theory to analyze the optimal macro/micro BS
(base station) density for energy-efficient heterogeneous cellular networks with QoS …

Energy-efficient base station (BS) operation is a key design goal in green cellular networks.
An effective way for energy conservation of BSs is to switch BSs on/off according to the traffic …

Given the explosive growth of mobile subscribers, network operators have to densely deploy
base stations to serve the exponentially increasing access demands. Nevertheless, recent …

Adding Femto Base Stations (FBSs) has become a common approach toward capacity and
coverage enhancements in the current cellular networks. Moreover, rapidly growing demand …

With the explosive proliferation of mobile devices and services, the user density of large-
scale cellular networks continues to increase, which results in further escalating traffic …
