Virtualization is the trend for the future mobile networks. With the advantage of virtualization, we can abstract the physical mobile network into the virtual network function (VNF) and design the network without the details. In this paper, we focus on the virtualization of the physical resources so that the resource allocation scheme considers not only the time-varying characteristic of wireless...
Soft Defined Network (SDN) and content caching are believed as two promising technologies in the future Radio Access Network (RAN) architecture of mobile communication system. Taking advantages of SDN enabled RAN architecture, we propose a QoS guaranteed resource allocation scheme with content caching. To evaluate the performance of content caching in RAN, we choose the effective capacity as the metric...
