Abstract
It is widely acknowledged that the forthcoming 5G architecture will be highly heterogeneous and deployed with high degree of density. These changes over the current 4G bring many challenges on how to achieve an efficient operation from the network management perspective. In this paper, we introduce revolutionary vision of the future 5G wireless networks, in which operating the wireless networks is no longer limited by hardware or even software. Specifically, by the idea of virtualizing the wireless networks, which has recently gained increasing attention, we introduce the everything-as-a-service (XaaS) taxonomy to light the way towards designing the service-oriented wireless networks. The concepts and challenges along with the research opportunities for realizing XaaS in wireless networks are overviewed and discussed.
