Abstract

“Green ICT” means Information and Communications Technology friendly for the globe. To stop global warming and climate change, ICT, with low emission of carbon dioxide thus low consumption of energy, is required. When there was no constraint of low energy consumption in communications, one solution for making us happier and more comfortable from the information-transmission perspective was to have a “stupid network” in which communication entities can handle just higher data transmission rates with no intelligence. However, once the constraint is imposed, an “intelligent network” is required as another solution in which the entities can intelligently reduce their energy consumption as much as possible while satisfying users’ needs.
