无线网络虚拟化和信息中心网络(ICN)是下一代无线网络中两项很有前途的技术。传统上,这两种技术是分开处理的。本文论证了将无线网络虚拟化与ICN联合考虑是必要的。具体而言,我们提出了一个以信息为中心的无线网络虚拟化框架,以实现无线网络虚拟化和ICN。然后,我们将虚拟资源分配和网络内缓存策略作为一个优化问题来制定,同时考虑了服务最终用户所获得的收入和租赁基础设施的成本。此外,根据分布式凸优化的最新进展,我们开发了一种基于交替方向乘法器(ADMM)的分布式虚拟资源分配和网络内缓存方案。仿真结果表明了该方案的有效性。
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 the end users but the cost-of-leasing infrastructure as well. In addition, with recent advances in distributed convex optimization, we develop an efficient alternating direction method of multipliers (ADMM)-based distributed virtual resource allocation and in-network caching scheme. Simulation results are presented to show the effectiveness of the proposed scheme.
