Energy-aware Umts Core Network Design

چکیده
According to several studies, telecom operators account for a not negligible power consumption, and several initiatives are being put into place to reduce the power consumption of the ICT sector in general. To this goal, we propose a novel approach to switch off some portions of the UMTS core network while still guaranteeing full connectivity and maximum link utilization. After showing that the problem falls in the class of capacitated multi-commodity flow problems, and therefore it is NP-complete, we propose some heuristic algorithms to solve it. Results show that it is possible to reduce the number of links and nodes currently used by up to 30% and 50% respectively during off-peak hours while offering the same service quality.
