Energy consumption analysis of C-RAN architecture based on 10G EPON front-haul with daily user behaviour

Cloud Radio Access Network (C-RAN) is a novel network architecture, which can solve many challenges of operators when facing the ever-increasing user demands. Specially, the operating expense (OPEX) of C-RAN is an issue of common concern. In this paper, we evaluate the energy consumption of the architecture based on a 10G EPON front-haul considering the daily user behaviour. The simulation results present the energy consumption distributions of C-RAN with daily user behaviour and in different quality of service (QoS). ? 2015 IEEE.E
