The rapid growth in cloud service demand has led to the establishment of large-scale virtualized data centers. However data centers consume a large amount of energy resulting in high operating costs and contributing to significant greenhouse gas (GHG) emissions. In cloud computing systems, users' demands are met through deployment of Virtual Machines (VMs) on Physical Machines (PMs). We propose to...
In cloud computing systems, users' demands are met through deployment of Virtual Machines (VMs) on Physical Machines (PMs).

Cloud computing is a new computing paradigm which has the provision of computational resources like services accessed over the internet. In this paradigm, computing resources are pooled and allocated according to customer demand. The growing demand for this new type of service has led to increased use of energy on the part of service providers, due to the need to maintain the computing infrastructure,...
This paper aims to investigate the scheduling problem of a mixed task set in a real-time system. When a mixed task set is executed, a scheduling algorithm should consider system energy consumption and the average response time of aperiodic jobs. This paper proposes the Ratio-based Aggressive Reclaim Algorithm} (RARA) that reclaims unused execution time left by earlier-completed jobs and possible slack...
It is estimated that the ICT industry contains not less than one billion personal computers (PC), with power consumption ranging from 100 to 200 W per workstation. Virtualization and Thin Client technologies, mediated by broadband network links will have a very significant impact on efforts to reduce energy consumption and to enhance data security throughout the ICT industry. Besides, virtualization...
The advent of cloud systems has spurred the emergence of an impressive assortment of Internet services. Recent pressures on enhancing the profitability by curtailing surging dollar costs on energy have posed challenges to, as well as placed a new emphasis on, designing energy-efficient request dispatching and resource management algorithms. What further adds to the design challenge is the highly diverse...
A class of research, which explores energy saving via the accuracy-performance tradeoff ability of applications with soft outputs, is emerging. Many such applications implement various notions of precision improvement in their iterative computations and output approximated results. Computing more precisely often requires greater computational effort, hence there is a tradeoff space between precision...
In cooperative content distribution (CCD), every Mobile Terminal (MT) cooperate with each other to distribute the content to those terminals which are within their transmission range and are interested in the same content. It has been already proved that CCD is more energy efficient than the traditional approach where each MT download the whole content individually. In this paper, queuing theory has...
The combined effect of Moore's law and the failure of Den nard scaling have led to multi-core mobile devices with immense computation capabilities. The biggest limitation of the computation capability for any mobile device is its battery. Mobile cloud computing is used to offload compute intensive tasks that affect a mobile device's battery. Mobile ad-hoc computing can be used as an alternative to...
The widespread deployment of varying networking technologies, coupled with the exponential increase in end-user data demand, have led to the proliferation of multi-homed or multi-interface enabled devices. To date, these interfaces are mainly utilized one at a time based on network availability, cost, and user-choice. While researchers have focused on simultaneously leveraging these interfaces by...
With raising concerns about global warming and environmental impacts of Greenhouse Gases (GhGs) emissions, energy efficiency and carbon footprint reduction attracted many researchers to provide efficient models and tools for energy, carbon, and cost estimation and management. In this paper, a model for measuring the energy consumption and carbon footprint of an individual virtual machine is presented...
Video-on-demand has been emerging as a very popular internet service in recent years. But energy consumption is becoming a critical issue as these services scale up. In this paper, we propose an energy-aware server provisioning strategy which dynamically turns on/off servers in order to adaptively tailor active servers to dynamic user load. We initiate a stochastic model which characterizes unique...
Commercial office buildings with renewable energies are becoming more important in the actual context. That integration cannot be seen isolated from the strategic transport planning. Under this context this paper presents an office facility, equipped with renewable energy sources, where the users can recharge their plug-in electric vehicles, using the available renewable power. The system controller...
Main memory power in volume and mid-range servers is growing as a fraction of total system power. The resulting energy consumption increases system cost and the heat produced reduces reliability. Emergent memory technology will provide systems with the ability to dynamically turn-on (online) and turn-off (offline) memory devices at runtime. This technology, coupled with slack in memory demand, offers...
