Virtual resource allocation in information-centric wireless virtual networks

Wireless network virtualization and information-centric networking (ICN) are two promising technologies in next generation wireless networks. Traditionally, these two technologies have been addressed separately. In this paper, we show that jointly considering wireless network virtualization and ICN is necessary. Specifically, we propose an information-centric wireless network virtualization framework for enabling wireless network virtualization and ICN. Then, we formulate the virtual resource allocation and in-network caching strategy as an optimization problem, considering not only the revenue earned by serving end users but also the cost of leasing infrastructure. In addition, with recent advances in distributed convex optimization, we develop an efficient distributed method based on alternating direction method of multipliers (ADMM)-based to solve virtual resource allocation and in-network caching scheme. Simulation results are presented to show the effectiveness of the proposed scheme.
