| Abstract | In wireless network virtualization, the isolation between MVNOs which is how to divide the resources between MVNOs without affecting each other is a challenging problem. In this paper, we propose one approach to achieve this isolation problem. Fraction of radio resources is allocated to each MVNO proportionally according to its number of users which changes over time. Moreover, we consider the backhaul topology of small cell and macro cell base stations. We formulate the joint resource allocation and user association as an optimization problem to maximize the sum rate of users and solve it by nonconvex alternating direction method of multipliers (NC-ADMM) method. Then, simulation is performed to show that the proposed approach is better than the fixed allocation of radio resources. |
