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.
