Optimizing Virtual Networks for Greener Computing

The importance of reducing the GHG gases and decreasing the Carbon footprint of any industry is not hidden to anybody to avoid global warming and its negative impacts on environment. Information Technology as a part of global industry has its share in this process. However IT shares is around 2% now, but it is growing with general growth of IT infrastructure and usage in different areas. One of ways to decrease Carbon footprint in data centers is to use sustainable source of energies for their power supply. Because the sustainable energies are not available everywhere and all the time and the fact that data transfer is cheaper than energy transfer, for power supplying the data centers with green energy, the whole datacenter should migrate to near a source of green energy according to a optimized schedule provided by a heuristic optimizer hypervisor which minimize the use of non-green energy.

Renewable Energy Provisioning for ICT Services in a Future Internet

Abstract. As one of the first worldwide initiatives provisioning ICT (Information and Communication Technologies) services entirely based on renewable energy such as solar, wind and hydroelectricity across Canada and around the world, the GreenStar Network (GSN) is developed to dynamically transport user services to be processed in data centers built in proximity to green energy sources, reducing GHG (Greenhouse Gas) emissions of ICT equipments. Regarding the current approach, which focuses mainly in reducing
