Power-saving control framework for cloud services based on set-top box

Recently, the more regulations of energy conservation have been emphasized, the more home appliance manufactures have made competitive efforts to improve the energy efficiency of their products. However, there have been no correlation analysis between energy-efficient home appliances and cloud technologies. While cloud services have been rapidly adopted in many service areas to guarantee a high return of investment (ROI) for service providers, Previous studies on power saving have been conducted to reduce the standby power consumption for home appliances, like a set-top box (STB), which can be worked as a thin client for cloud services, or have only shown power models of a virtual machine (VM) on the cloud side without considering the power consumption states of its corresponding thin clients As a result, this paper proposes a power-saving control framework (PSCF) that consumes low power levels for both on the cloud side and on a STB efficiently for providing cloud services. The experimental result shows that the proposed framework outperforms the experiment not applied with any other power saving method for cloud services in terms of power efficiency.
