Issues and prospects for energy saving networks

Studies on existing and future networks aimed at building an energy saving networks have been conducted by global standard groups such as GreenTouch, IETF, and ITU-T. Future networks deployed without considering energy issues will encounter major problems related to network maintenance and operating costs, and ICT has been a recent area of interest with respect to saving energy. Sensor networks/ad hoc networks have been studied for a number of years in efforts to overcome battery constraints. Meanwhile, research on reducing the overall energy dissipation at the network level has been conducted by GreenTouch. In this paper, we introduce research issues and prospects for energy saving networks.
