A novel design of Cognitive Wireless Networks: Architecture and testbed

Cognitive Wireless Network (CWN) is a set of heterogeneity networks designed to perceive and learn from current multi-domain environment, then plan and decide a scheme based on the end-to-end goals. It aims to satisfy the integration, ubiquity and broadband requirements of future networks. With the complexity of heterogeneity networks rising, the need to manage this complexity makes the realization of CWN well-timed and attractive. Many related projects to do further study have been built by research teams. During the past few years, we are working on a project called “Basic theory and Key Technologies in Cognitive Wireless Networks”. It is one of the major projects in National Basic Research Program (973 Program) approved by the Chinese government. Our research team concentrates on issues including network architecture, multi-dimension sensing technologies and radio resource management which are connected with each other. In this article, an overview of this project will be shown by introducing its purpose, research vision, research progress, and testbed.
