In the research of green networks, considering the base station (BS) density from the
perspective of energy efficiency is very meaningful for both network deployment and BS …

Network densification has emerged as a powerful paradigm to boost spectral efficiency and
accommodate the continual rise in demand for wireless capacity. In dense cell deployments …

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 …

In this paper, we focus on reducing the on-grid energy consumption in heterogeneous radio
access networks (HetNets) supplied with hybrid power sources (grid and renewables). The …

In the landscape of next-generation cellular networks, a projected surge of over 12 billion
subscriptions foreshadows a considerable upswing in the network's overall energy …

Cell switch-off (CSO) is an important approach to reducing energy consumption in cellular
networks during off-peak periods. CSO addresses the research question of which cells to …

The energy consumption of mobile networks is already substantial nowadays, and only
expected to further increase with the roll-out of 5G. Base stations are the key elements in this …

Energy-efficiency, one of the major design goals in wireless cellular networks, has received
much attention lately, due to increased awareness of environmental and economic issues …

To enhance the utilization of base stations (BSs) and face the challenge of the upcoming
mobile data tsunami, energy saving and traffic offloading are two important issues to …

We investigate the energy efficiency in the downlink of a two-tier heterogeneous cellular
network with quality of service consideration. By modeling the distributions of the macrocell …
