Über dieses Buch

This SpringerBriefs is an overview of the emerging field of wireless access and mobile network virtualization. It provides a clear and relevant picture of the current virtualization trends in wireless technologies by summarizing and comparing different architectures, techniques and technologies applicable to a future virtualized wireless network infrastructure. The readers are exposed to a short walkthrough of the future Internet initiative and network virtualization technologies in order to understand the potential role of wireless virtualization in the broader context of next-generation ubiquitous networks. Three main wireless virtualization perspectives are explored, along with the potential challenges and requirements of a sustainable wireless virtualization framework. Finally, it presents an example of a multi-perspective wireless virtualization framework. The readers learn the latest concepts in the application of wireless virtualization as well as its relationship with cutting-edge wireless technologies such as software-defined radio (SDR) and cognitive radio.

Chapter 1. Introduction
Abstract
Hardware virtualization is a well-applied concept, particularly in the field of computing technologies. It involves the abstraction and sharing of hardware resources among different parties. Virtual memory systems and virtual machines are features present in modern computers and operating systems that are often referred to as server or host virtualization. However, the quest for virtualization does not end here. In recent years, the constant growth of wireless access technologies highlights its potential as a powerful extension to the wired infrastructure. Thus, it is undeniable that the future of digital communications will heavily rely on wireless technologies. As the virtualization trend progresses, the decision to bring virtualization to the wireless access is now being considered.

Chapter 2. Network Virtualization: Overview
Abstract
Before presenting different network and wireless virtualization architectures and techniques, this chapter summarizes what other existing surveys on similar topics have already covered. However, the readers might wonder why network virtualization is discussed in great details in a book on wireless virtualization? In fact, the so-called wireless virtualization borrows many concepts and benefits from network virtualization. Additionally, wireless virtualization must coexist within the context of network virtualization in most applications. One of the goals of the first half of this book, is to highlight different concepts and implementation technologies used in network virtualization that can be relevant, applied, integrated or extended to wireless virtualization.

Chapter 3. Network and Infrastructure Virtualization Architectures
Abstract
This chapter covers virtualization applied in the context of meta-architectures and next-generation network (NGN) testbeds, which can also be referred to as testbed virtualization. In this chapter, the main focus is on the organizational architecture and the management framework of such architectures. It mainly describes the specifications of large testbeds from existing national and international research initiatives on Future Internet network architectures. Overall, this chapter provides a “big picture” and a context in which wireless virtualization can ultimately be integrated in. While many of these architectures do not explicitly address wireless virtualization, they do provide some universal design principles for a virtualized infrastructure. Additionally, the importance of wireless technologies in the Future Internet architecture is clearly recognized. Ultimately, a framework for wireless infrastructure virtualization can be derived based on the concepts summarized in this chapter.

Chapter 4. Network Virtualization Technologies and Techniques
Abstract
This chapter continues with the discussion of network virtualization implementations and enabling technologies applicable within the context of wireless virtualization. More specifically, recent developments in software-defined networking (SDN) technologies are presented. Overall, SDN concepts are used to relocate functionalities from hardware into software by providing configurable interfaces. This increases the programmability of the hardware and facilitates the implementation of virtualization.

Chapter 5. Wireless Virtualization
Abstract
This chapter is focused on presenting the different aspects of wireless virtualization such that the readers can acquire a better understanding of the context in which it is applied. The different aspects discussed in this chapter include the role of multiple access techniques in virtualization, the integration of wireless resources in testbed architectures, the applications enabled by a virtualized wireless infrastructure and the virtualization of different wireless technologies.

Chapter 6. Framework for Wireless Virtualization
Abstract
Since different aspects of wireless technologies are relevant for different services and applications, there are various approaches to wireless virtualization. A particular approach that is beneficial to a certain application can be detrimental to another. As there are different advantages and disadvantages of a fully virtualized system, a progressive virtualization framework that focuses on the coexistence of different virtualization perspectives is proposed.
