Research on Cognitive Wireless Networks: Theory, Key Technologies and testbed

Cognitive Wireless Network (CWN), which is a set of heterogeneity networks with the capability of perceiving, planning, deciding and learning according to current multi-domain environment and end-to-end goals, is motivated by the integration, ubiquity and broadband requirements of future networks. But the rising complexity of heterogeneity networks and the need to manage this complexity make the actualization of CWN timely and attractive. Many related projects are built for research teams to do further study. We are undertaking a project called “Basic theory and Key Technologies in Cognitive Wireless Networks” which is one of the major projects in National Basic Research Program (973 Program) approved by the Chinese government. Our research team focuses on issues from network architecture to multi-dimension sensing technologies and radio resource management which are related to each other. In this article, an overview of this project is given by discussing its purpose, research vision, research progress, and testbed.
