Network virtualization and resource description in software-defined wireless networks

摘要

Future networks will be defined by software. In contrast to a wired network, the software defined wireless network (SDWN) experiences more challenges due to the fast-changing wireless channel environment. This article focuses on the state-of-the-art of SDWN architecture, including control plane virtualization strategies and semantic ontology for network resource description. In addition, a novel SDWN architecture with resource description function is proposed, along with two ontologies for the resource description of the latest wireless network. Future research directions for SDWN, control strategy design, and resource description are also addressed.
