With the development of cloud computing, high energy consumption issue has attracted more and more attentions recently. To achieve the goal of energy conservation, accurately measuring the power consumption of distributed resource is of significant importance. Conventional power models can only provide fine-grained power measurement for physical devices instead of virtualized resources. In this...

The increasing cost of energy and the worldwide desire to reduce CO2 emissions has raised concern about the energy efficiency of information and communication technology. Whilst research has focused on data centres recently, this paper identifies office environments as significant consumers of energy. Office environments offer a great potential of energy savings, given that office hosts often r...

In cloud computing, a cloud is a managed pool of resources which provide on-demand services or computational resources to the remote users over a network. The resources are provided to users in the form of virtual machines and are possibly distributed and heterogeneous, running on the cloud environment over Internet. Energyaware Scheduling algorithm and Energy-aware Live Migration algorithm red...

Cloud Computing, the long-held dream of computing as a utility, has the potential to transform a large part of the IT industry, making software even more attractive as a service and shaping the way IT hardware is designed and purchased. Virtualization technology forms a key concept for new cloud computing architectures. The data centers are used to provide cloud services burdening a significant...

Cloud Computing offers indispensable infrastructure for storage and computing facilities for development of diversified services. The large utilization of resources leads to increased energy consumption that has imposed a limit on performance growth. Owing to high operational costs and carbon dioxide footprints, an efficient energy management technique needs to be developed and deployed that re...

Networks of distributed microsensors are emerging as a compelling solution for a wide range of data gathering applications. Perhaps the most substantial challenge facing designers of small but long-lived microsensor nodes is the need for significant reductions in energy consumption. We propose a power-aware design methodology that emphasizes the graceful scalability of energy consumption with f...

Increasingly tight energy design goals require processor architects to rethink the organizational structure of microarchitectural resources. In this paper, we examine a new multilateral cache organization that replaces a conventional data cache with a set of smaller region caches that significantly reduces energy consumption with little performance impact. This is achieved by tailoring the cach...

Mobile games and other mobile graphics applications have become popular because untethered computing is convenient and ubiquitous entertainment is compelling. However, rendering graphics on mobile devices faces challenges due to limited system resources, such as battery energy, low memory and disk space. Real time frame rates, low energy consumption and high image quality are all desirable attr...
