Abstract
Network virtualization covers aspects like resource virtualization and slicing. The virtualization of the physical resources consists of implementing multiple instances of a required logical resource on a single machine/node within the same or different set of physical resources allocated to the Virtual Network (VNet), the slice. Sharing radio resources on multiple access schemes has been intensively investigated for wireless systems concerning the separation of the radio links for different end-users of the same system. This chapter discusses the relevant aspects of radio resources management (RRM) and cooperative radio resources management (CoRRM) and radio resource sharing and wireless-virtualization-related work. It presents the network architecture, the model description, the strategies and algorithms for VNet radio resource allocation. The chapter also presents the results for Average Cluster Data Rate and Average Cluster Utilization. Regarding the Average Cluster Serving Data Rate, it is observed that it decreases slightly with the number of GRT virtual base stations (VBSs).
