Energy Aware Networking

While ICT is seen as a large part of the solution towards reducing the world’s carbon footprint (e.g., video-conferencing reducing air-miles, dynamic energy monitoring and control, multi-modal transport logistic solutions, etc.), ICT in itself needs to become more energy efficient. For example the EU Commission is pushing for ICT to reduce its own carbon footprint by 20% by 2015. Energy Efficient ICT refers to all efforts to "Green” ICT, to reduce power consumption and carbon emissions of ICT networks and systems. Given the growth rate in internet traffic, this is important both for environmental and financial reasons.

In NIC in DCU energy efficient ICT research covers a multitude of work from wired to wireless technologies, physical to application layer schemes, from energy-saving network-wide schemes to saving energy at individual component level, all for future next generation networks.
