Description
Summary:Summary Worldwide mobile broadband communications networks are increasingly contributing to global energy consumption. In this paper we tackle the important issue of energy saving by enhancing the energy efficiency of mobile broadband systems thereby reducing CO 2 emissions. We first provide a holistic system view aiming at ensuring that any proposed solutions to improve energy efficiency do not degrade the energy efficiency or performance on any other part of the system. Then, we present a novel scheduling algorithm that improves the scheduling energy efficiency in OFDMA-based wireless cellular networks. Our goal is to reduce the overall downlink energy consumption while adapting the target of spectral efficiency to the actual load of the system and meeting the Quality of Service. Our analysis reveals how the proposed approach permits to achieve notable energy gain over traditional scheduling algorithm especially in not saturated scenarios.
