A SMDP Based Virtual Resource Allocation Model for Multimedia Services in 5G Network

Resource virtualization is considered as a potential technique to cope with the mushroomed multimedia services. With resource virtualization, physical resources are characterized as virtual resource shared by various Service Providers (SPs). In this paper, we focus on the virtual resource allocation problem for multimedia service in 5G network. The system rewards is maximized with the considerations of the system virtual resource consumption and the incomes generated from mobile users. To address this issue, a Multimedia Service Admission Model (MSAM) based on Semi-Markov Decision Process (SMDP) is proposed to characterize the system rewards. Then the steady-state probability and service request blocking probability are derived. Numerical results show that theoretic results are consistent with the simulation results.
