Performance Evaluation of Cloud Radio Access Network with Hybrid Power Supplies

With the unprecedented augmentation of mobile communications and the advancement of new technologies, energy efficiency (EE) has developed a severe apprehension of maintaining the profitability of telecom operators by means of reducing the operational expenditure with minimum atmospheric deterioration as well. Base stations (BSs) are the prime energy consumer in the telecom sector. Therefore, reducing the energy consumption of BSs in the cellular networks has recently become a great concern by the telecom operators and researchers. As a consequence, attempts have been taken behind reducing BS energy consumption and to find expedient ways for better EE. In this paper, we propose renewable energy powered cloud radio access network (C-RAN) architecture for achieving long term sustainable green cellular networks. Several performance metrics under the telecommunication system namely equipment level and network-level are investigated in the design framework aiming to enhance overall EE. Moreover, MATLAB based Monte-Carlo simulations have been accomplished for checking out EE performance of the introduced network fluctuating system criterions for example transmission bandwidth, the number of the transceiver, solar module capacity, etc. in the context of realistic traffic intensity. Analytical outcomes validate the performance of the recommended system over the conventional one.
