This paper investigates the dynamic resource provisioning with queue stability in wireless virtualized networks (WVN). Aiming to maximize the total average rate of WVN over a transmission frame, a dynamic resource provisioning policy is proposed, while a minimum average required rate of each slice and a stable-queue constraint of WVN are preserved. Based on Lyapunov drift-plus-penalty algorithm and variable transformation techniques, an iterative algorithm is proposed for joint power and sub-carrier allocation. Performance of the proposed algorithm is evaluated by simulations performed investigate the effects of various system parameters on the average rate of WVN and queue stability.
