Abstract:
In order to tackle the issues of mounting deployments and large energy consumption of base stations, it is integral to devise schemes to improve energy efficiency in cellular networks. We propose a virtualized network function of cell management on an SDN architecture. We develop a cell management algorithm on the architecture that can effectively control the sleep and awake modes of base stations and perform handover operations in a cellular network. It provides significant benefits over current cellular networks that suffer from inflexible management and complex control. Our extensive trace-driven evaluation results show that the proposed control architecture and the cell management algorithm achieve significant energy savings, and incur less control message exchanges, more cells in a sleep mode for longer durations, and less cell status changes than existing energy saving approaches for cellular networks.
