Dynamic Spectrum Sharing in the Age of Millimeter-Wave Spectrum Access [PDF]
IEEE Network, 2020 Next-generation wireless networks are facing spectrum shortage challenges, mainly due to, among other factors, the projected massive numbers of IoT connections and the emerging bandwidth-hungry applications that such networks ought to serve. Spectrum is scarce and expensive, and therefore, it is of crucial importance to devise dynamic and flexible ...

On Dynamic Spectrum Allocation in Geo-Location Spectrum Sharing Systems
IEEE Transactions on Mobile Computing, 2019 Spectrum sharing is a key technology to relieve the ever-increasing spectrum demand and realize the full potential of radio spectrum. In this paper, we study spectrum sharing between higher priority users and lower priority users under geo-location based spectrum sharing systems.

User-Centric Spectrum Sharing in Dynamic Network Architecture [PDF]
2016 IEEE Globecom Workshops (GC Wkshps), 2016 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 ...

Efficient dynamic spectrum sharing through rate compensation and spectrum handoff [PDF]
2013 Proceedings IEEE INFOCOM, 2013 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.

Cross-Layer Design in Dynamic Spectrum Sharing Systems
EURASIP Journal on Wireless Communications and Networking, 2010 We consider a dynamic spectrum sharing system consisting of a primary user, whose licensed spectrum is allowed to be accessed by a secondary user as long as it does not violate the prescribed interference limit inflicted on the primary user.
