Green I: Energy Efficient Wireless Networks

Keynote: Prof Luiz Da Silva (9:00-9:35)
Chair: M. Majid Butt (Trinity College Dublin, Ireland)
Keynote Title: When Mobile Operators Share Their Networks: Network Planning, Energy Considerations, and Performance Efficiencies:
Abstract: Green wireless networks strive to minimize their energy consumption, while enabling a range of services that help decrease overall carbon emissions, from tele-presence to the smart grid. A significant contributor to the energy consumption of current mobile networks is the deployment and operation of fixed infrastructure. Such energy costs can be significantly reduced through network sharing among mobile operators. In this talk we will discuss the impact of infrastructure sharing on the evolution of wireless networks, taking into account cost structures and regulatory measures to ensure competition in the mobile services market. We will also present some results on the performance efficiencies obtained through sharing, including gains in network coverage and capacity. We believe that network sharing will increasingly rely on virtualization and resource slicing: in the Horizon 2020 project WiSHFUL we are starting to experiment with spectrum virtualization using a software defined radio platform.

Keynote Title: Energy Procurement for Cellular Networks with Uncertain Renewable Energy Generation
Abstract: Renewable energy (RE) is an emerging solution for reducing carbon dioxide (CO2) emissions from cellular networks. One of the challenges of using RE sources is to handle its inherent uncertainty. We discuss in this talk, RE powered cellular networks. More specifically, we explain how to design cellular networks that aim to reduce energy procurement costs from the smart grid by optimizing the amounts of energy procured from their locally deployed RE sources as well as from the smart grid. In addition, we present approaches that aim to determine the extra amount of energy to be sold to the electrical grid at each time period. We also present, chance constrained optimization as a suitable tool to deal with the randomness in the RE generation. We conclude our talk by offering some selected simulation results analyzing the effect of the uncertainty and comparing the different approaches for various scenarios of interest.
