Data centers are critical, energy-hungry infrastructures that run large-scale Internet-based
services. Energy consumption models are pivotal in designing and optimizing energy …

This work presents an estimation of the global electricity usage that can be ascribed to
Communication Technology (CT) between 2010 and 2030. The scope is three scenarios for …

Virtualization technology is the underlying element of cloud computing. Traditionally, cloud
computing has employed virtual machines to distribute available resources and provide …

In the current decade, doing the search on massive data to find “hidden” and valuable
information within it is growing. This search can result in heavy processing on considerable …

With an objective to provide the proactive and personalized services for human beings,
Cyber-Physical-Social Systems (CPSS), which combine the cyber space, physical space …

Abstract Dynamic Voltage and Frequency Scaling (DVFS), CPU pinning, horizontal, and
vertical scaling, are four techniques that have been proposed as actuators to control the …

Software power estimation of CPUs is a central concern for energy efficiency and resource
management in data centers. Over the last few years, a dozen of ad hoc power models have …

In this paper, analytical models, based on the stochastic reward nets (SRNs), are proposed
to analyze the impact of resource allocation algorithms and process migration methods on …

The number of data centers and the energy demand are increasing globally with the
development of information and communication technology (ICT). The data center operators …

In this article we examine a specific version of the temporal bin packing problem (TBPP) that
occurs in job-to-server scheduling. The TBPP represents a generalization of the well-known …
