This paper considers a cellular network with base stations (BSs) powered by heterogeneous
energy sources, ie, besides conventional BSs connected to the power grid, some BSs are …

Energy efficiency of cellular networks can be greatly improve if base stations (BSs) can be
put into a low power operation mode during low load periods. In this paper, we present a …

Switching off some Base Stations (BSs) with low traffic is a promising approach to save
energy in cellular networks. However, it should be noted that frequently switching BSs on/off …

Base station (BS) sleeping operation in transient process has been widely analyzed in
current studies to save cellular network energy consumption. In this paper, we propose a …

The energy consumption of information and communication technology (ICT) industry has
become a serious problem, which mostly comes from the network infrastructure, rather than …

Base station (BS) sleeping is an effective way to improve the energy-efficiency of cellular
networks. However, it may bring extra user-perceived delay. We conduct a theoretical study …

The energy consumption of the information and communication technology (ICT) industry,
which has become a serious problem, is mostly due to the network infrastructure rather than …

In this paper, we investigate how to utilize renewable energy harvested by small cells to
increase network capacity. Specifically, we try to maximize the average capacity of a small …

The traffic load of cellular networks varies in both time and spatial domains, causing many
base stations (BS) to be under-utilized. Assisted by cell zooming, dynamic BS sleep control …

We consider energy-efficient wireless resource management in cellular networks where
base stations (BSs) are equipped with energy harvesting devices, using statistical …
