Application-Oriented Dynamic Spectrum AccessOn-Demand Spectrum Access


With the proliferated growth of wireless communication services, the radio spectrum has become a precious resource. On the other hand, many licensed spectrum bands are considerably under-utilized in both time and spatial domains. This situation has motivated extensive research on cognitive radio and dynamic spectrum access to increase spectrum utilization.

The major goal of the project is to develop novel architectures and algorithms for dynamic spectrum access in cognitive radio networks, to eliminate the technical barriers for success of cognitive radio networks, through significantly improving the spectrum utilization, the security, and the data transport performance of cognitive radio networks. In particular, we develop an application-oriented dynamic spectrum access architecture, termed on-demand spectrum access (ODSA), for cognitive radio networks to offer on-demand spectrum services to users, such that users can dynamically set up application-oriented virtual topologies to carry out specific applications.
