Welcome to GreenComm'09!


The steadily rising energy cost and the need to reduce global CO2 emission to protect our environment are today's economical and ecological drivers for the emerging consideration of energy consumption in all fields of communications. Triggered by network operators experiencing energy cost as a significant new factor of their calculation, researchers have started to investigate approaches for reducing power consumption and manufacturers have started offering energy-efficient network components. Also standards bodies, such as the IEEE, are already developing standards for energy-efficient protocols. However, research and development in these areas is still at an early stage and the space of potential solutions is far from being explored.

The First International Workshop on Green Communications (GreenComm'09), held in conjunction with the IEEE International Conference on Communications (IEEE ICC 2009), will bring together academic and industrial researchers for discussing energy-efficient communications. It will close the gap between the already established conferences and workshops covering energy efficiency for IT on one side and for wireless sensor networks on the other side.

We see particular potential for reducing energy consumption in mobile and wireless access networks, broadband access networks, and home networks:

Broadband to the home is bringing to the fore the additional issue of power consumption in the home to access and use BB services and equipment. The European Commission is estimating that by 2012 the energy consumption in the home for BB fruition will reach 50 TWh, from basically 0 TWh in the year 2000. Of the 10% (electricity consumption) globally spent for ICT, already today 70% are spent in homes / offices and only 30% in the network / server farms. That means that energy consumed by the homes will be twice as large as the one consumed by networks to bring broadband into the homes. The operators may contribute to stem the increase of power consumption in the home by an intelligent control of residential energy from the network.

Data rates in wired and wireless networks are driven by "Moore's Law" and are thus rising by a factor of roughly 10 every 5 years. The price paid for this enormous growth is a doubling of the power consumption in cellular networks infrastructure (base stations and core network) every 4-5 years - to 60 TWh (billion kWh) in 2007. The radio access network accounts for 80% of this energy consumption. In developing countries, operators now spent more than half of their OPEX only for the diesel required to keep base station generators up and running. Increasing the energy efficiency of base stations has thus become a key challenge of mobile networks operators.
