Base-Station Sleep Management in Open-Access Femtocell Networks
IEEE Transactions on Vehicular Technology, 2016In this paper, we focus on enhancing the energy efficiency in open-access femtocell networks where many femto base stations (BSs) are deployed in a large public area such as airports, shopping malls, etc. In those areas, the femtocells are overlapped and underutilized during most of the operation time because femto BSs are densely deployed to support ...

Traffic-aware base station sleeping in dense cellular networks
2010 IEEE 18th International Workshop on Quality of Service (IWQoS), 2010The energy consumption of information and communication technology (ICT) industry has become a serious problem, which mostly comes from the network infrastructure, rather than the mobile terminals. In this paper, we consider densely deployed cellular networks where the coverage of base stations (BSs) overlaps and the traffic intensity varies over time ...

Small Cell Base Station Sleep Strategies for Energy Efficiency
IEEE Transactions on Vehicular Technology, 2016Small cell networks offer a promising and viable approach to meeting the increasing demand for high-data-rate wireless applications. With the expected increase in the number of small cell deployments, energy efficiency (EE) is a crucial system design parameter that demands consideration from an eco-sustainability perspective.

Traffic Adaptive Base Station Sleeping Control in Inhomogeneous Network
2018 Annual IEEE International Systems Conference (SysCon), 2018Base station (BS) sleeping operation in transient process has been widely analyzed in current studies to save energy consumption in 5G cellular network. In this paper, we proposed a two-stage BS sleeping scheme with traffic offloading to reduce the energy consumption in inhomogeneous cellular networks with spatio-temporal random arrival of traffic.

Rewarded Access to a Sleeping Base Station
IEEE Communications Letters, 2015This letter proposes a rewarded access scheme that facilitates access of users to a sleeping base station (BS). In our system, an accessing user can wake up the sleeping BS upon his arrival and decides to join or balk, if his reward is greater than or equal to his waiting cost caused by set-up times of the sleeping BS.

On energy-delay tradeoff in base station sleep mode operation
2012 IEEE International Conference on Communication Systems (ICCS), 2012Base station (BS) sleep mode operation is one of the effective ways to save energy, but it may lead to longer delay to the customers. In order to evaluate the tradeoffs between energy consumption and customer delay, we model the BS sleep mode operation as an N-policy M/G/1 vacation queue with setup and close-down times, where the BS enters sleep mode ...

On the energy efficiency of base station sleeping with multicell cooperative transmission
2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011Switching underutilized base stations (BSs) to sleep mode is recognized as a promising approach to reduce energy consumption of cellular networks, but it may increase the transmit power of remaining active BSs to guarantee service coverage. Coordinated multi-point (CoMP) can effectively reduce transmit power of BSs through BS cooperation but requiring ...

Optimal Operation of Base Stations With Deep Sleep and Discontinuous Transmission
IEEE Transactions on Vehicular Technology, 2018Traffic-aware base station (BS) sleeping is a promising approach to increase the energy efficiency (EE) of cellular networks. Both deep sleep and discontinuous transmission (DTX) can be applied to improve network EE. This paper studies the optimal BS operation when both deep sleep and DTX are employed.

Sleep control for base stations powered by heterogeneous energy sources
2013 International Conference on ICT Convergence (ICTC), 2013This paper considers a cellular network with base stations (BSs) powered by heterogeneous energy sources, i.e., besides conventional BSs connected to the power grid, some BSs are purely powered by the renewable energy. BS sleep is introduced not only to save grid power, but also to store renewable energy for future use when the temporal traffic ...
