Virtualization is a topic of great interest in the area of mobile and wireless communication systems. However the term virtualization is used in an inexact manner which makes it difficult to compare and contrast work that has been carried out to date. The purpose of this paper is twofold. In the first place, the paper develops a formal theory for defining virtualization. In the second instance,...

-The Cloud computing offers dynamically scalable resources provisioned as a service over the Internet. It enables individuals and organization to use various services like software as a service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service(IaaS) over the Internet. Virtualization is the fundamental technology that powers cloud computing. Virtualization allows running multi...

At present, the mostly used and developed mechanism is hardware virtualization which provides a common platform to run multiple operating systems and applications in independent partitions. More precisely, it is all about resource virtualization as the term ‘hardware virtualization’ is emphasized. In this paper, the aim is to find out the advantages and limitations of current virtualization tec...

We introduce a virtualization technology into the control system as operator consoles. The virtualization technology is a hot topic for server computing. The virtualization technology enables to consolidate a lot of server computers to a few host computers and reduces system maintenance cost drastically. Recently a dozen of commercial and non-commercial virtualization products are proposed. We ...

Wireless testbed virtualization aims to provide a stable, reproducible, environment that is capable of simultaneously supporting multiple radio experiments in the same RF environment. Our study provides a brief overview of current effort in the direction of virtualization, and aspects affecting the feasibility of such setups. Our preliminary studies involve comparison of current virtualization ...

For the majority of common workloads, performance in a virtualized environment is close to that in a native environment. Virtualization does create some overheads, however. These come from the virtualization of the CPU, the MMU (Memory Management Unit), and the I/O devices. In some of their recent x86 processors AMD and Intel have begun to provide hardware extensions to help bridge this perform...
