Virtualization of wired networks and end computing
systems has become one of the leading trends in networked
ICT systems. In contrast relatively little virtualization has occurred
in infrastructure based wireless networks, but the idea
of virtualizing wireless access is gaining attention as it has the
potential to improve spectrum utilization and perhaps create
new services. In this paper we survey the state of the current
research in virtualizing wireless networks. We define and describe
possible architectures, the issues, hurdles and trends towards
implementation of wireless network virtualization.
