(English Abstract) |
Wireless network slicing (i.e., network virtualization) is one of the auspicious approaches to address the increasing demand of mobile data services for 5G wireless networks. It enables logical decoupling of the traditional cellular network into infrastructure providers (InPs) and mobile virtual network operators (MVNOs). It also offers a virtualized wireless network, efficient resource utilization, and isolation between network slices (i.e., between MVNOs). Here, we consider wireless network slicing for a single InP who owns radio resources and for multiple MVNOs who need radio resources to provide specific services to their mobile users. One of the challenges in wireless network slicing is how to efficiently allocate the limited radio resources available at the InP to the MVNOs. In this paper, we address the problem of efficient allocation of the InPs radio resources to the MVNOs which aims to maximize the total network capacity of the InP. To this end, we decompose our considered problem into two layers. The upper-layer is an efficient allocation of the InPs radio resources (bandwidth) to the MVNOs, and the lower-layer is an optimal allocation of MVNOs resources gained from the InP to their mobile users. We then propose a Generalized Kelly Mechanism framework and utilize the Karush-Kuhn-Tucker (KKT) conditions to solve the upperlayer and the lower-layer of our resource allocation problem, respectively. Finally, simulation results prove that the proposed algorithm outperforms other existing resource allocation schemes in virtualized wireless networks.
