Performance-to-Power Ratio Aware Virtual Machine (VM) Allocation in Energy-Efficient Clouds
2015 IEEE International Conference on Cluster Computing, 2015The last decade witnesses a dramatic advance of cloud computing research and techniques. One of the key faced challenges in this field is how to reduce the massive amount of energy consumption in cloud computing data centers. To address this issue, many power-aware virtual machine (VM) allocation and consolidation approaches are proposed to reduce ...

An Energy Efficient Charging Technique for Switched Capacitor Voltage Converters With Low-Duty Ratio
IEEE Transactions on Circuits and Systems II: Express Briefs, 2018Charging a capacitor array of a switched-capacitor (SC) dc-dc converter, supplying load circuits with a very short active period, can be pivotal to achieve high energy efficiency of its operation. This is because the capacitors may lose most of the stored energy during a long sleep period, and thus every sleep-to-active transition requires full ...

Balancing Energy Efficiency and Hit Ratio in Social-Aware Caching: A Cross Layer Approach
2019 IEEE Global Communications Conference (GLOBECOM), 2019Caching is a promising technique that can effectively reduce peak traffic by pushing popular content items proactively to the users during off- peak hours. Two key performance metrics for proactive caching are the energy efficiency and hit ratio. In this paper, we are interested in balancing the hit ratio and energy efficiency in social-aware proactive

Effect of Base Station-Sleeping Ratio on Energy Efficiency in Densely Deployed Femtocell Networks
IEEE Communications Letters, 2015In this paper, we focus on energy efficiency (EE) in densely deployed femtocell networks where a large number of open-access femto base stations (BSs) are deployed in a public hotspot area such as airport, shopping mall, etc. In such areas, femto BSs are underutilized during most of the operation time because they are deployed to support the peak ...

Science China Information Sciences, 2013
In cooperative communication, different ratio combining approaches can be utilized at the receiver based on the channel state information (CSI) available to the destination. In this paper, we focus on optimal energy allocation under amplify-and-forward (AF) cooperative communications when various ratio combining methods are utilized. More specifically,
