Energy Sustainable Traffic Aware Hybrid Powered Off-Grid Cloud Radio Access Network

The aggregate power supply of solar photovoltaic (PV) and diesel generator (DG) is an attractive solution for the next generation off-grid cellular network where the electricity is not available. In this paper, we emphasized on energy efficiency (EE) for cloud radio access network (C-RAN) architecture in the context of 5G cellular networks with hybrid supply. The intermittent nature of PV generation is counter balanced by the DG supply which has emerged as a promising option for energy sustainability. The prime aim is to maximum utilization of green energy harvested from installed PV panels for greener the envisioned network. In addition, the environmental effect such as carbon footprint has been comprehensively analyzed by varying solar capacity. An extensive simulation has been carried out for evaluating EE performance of the proposed network varying different system parameters such as transmission power, solar module capacity in consideration of the real traffic demand. Numerical results justify the effectiveness of the proposed scheme.
