Dynamic resource provisioning with stable queue control for wireless virtualized networks

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.
