Abstract
Mobile network virtualization is a promising technology due to its flexibility and feasibility. Since it enables physical resources abstraction and sharing, the overall resource inefficiency can be reduced dramatically. By means of virtualization, mobile service providers can share their physical resources with multiple virtual network operators. In this paper, a joint power and subchannel allocation algorithm for mobile network virtualization (MNV) with quality of services support is proposed. It presents a resource allocation scheme for orthogonal frequency division multiple access-based MNV with multiple virtual network operators. An optimal solution is provided to maximize the total data rate of both infrastructure providers and virtual network operators. Numerical results have shown that the proposed resource allocation algorithm improves the overall performance.
