Efficient dynamic spectrum sharing through rate compensation and spectrum handoff [PDF]
In this work, we propose a heuristic for dynamic spectrum sharing in cognitive radio networks. The concept of rate compensation is introduced so that cognitive radio users are able to achieve their rate requirement by performing adequately spectrum handoffs.

Towards Collaborative and Dynamic Spectrum Sharing via Interpretation of Spectrum Access Policies
This paper describes some of the challenges that need to be addressed in order to develop collaborative spectrum-sharing systems. The importance of these challenges stems from the assumption that rules for spectrum sharing can change after the deployment

User-Centric Spectrum Sharing in Dynamic Network Architecture [PDF]
Dynamic network architecture (DNA) has emerged as a promising networking paradigm which establishes a low-cost ubiquitous network connectivity without the need for significant changes in software and hardware infrastructure. In this concept the major player in spectrum sharing process is the user itself hence the name user-centric spectrum sharing ...

Dynamic primary-secondary spectrum sharing with cellular systems [PDF]
This paper considers primary-secondary spectrum sharing when the primary is a cellular system. Sharing is allowed if primary communications can withstand additional interference, rather than if there are no primary communications. We consider cases when primary and secondary systems cooperate (cooperative sharing) and when they do not (coexistent ...

Modified Gini Index Detector for Cooperative Spectrum Sensing over Line-of-Sight Channels
Recently, the Gini index detector (GID) has been proposed as an alternative for data-fusion cooperative spectrum sensing, being mostly suitable for channels with line-of-sight or dominant multi-path components.
