Efficient dynamic spectrum sharing through rate compensation and spectrum handoff [PDF]

open access: yes2013 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.

Towards Collaborative and Dynamic Spectrum Sharing via Interpretation of Spectrum Access Policies

open access: yesApplied Sciences, 2021
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]

open access: yes2016 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 ...

Dynamic primary-secondary spectrum sharing with cellular systems [PDF]

open access: yesProceedings of the 5th International ICST Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2010
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

open access: yesSensors, 2023
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.

Coordinated Allocation of Radio Resources to Wi-Fi and Cellular Technologies in Shared Unlicensed Frequencies

open access: yesIEEE Access, 2021
Wireless connectivity is essential for industrial production processes and workflow management. Moreover, the connectivity requirements of industrial devices, which are usually long-term investments, are diverse and require different radio interfaces. In
