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.

A dynamic spectrum access scheme for cognitive radio networks [PDF]
, 2009 —In this paper, the dynamic spectrum access problem for cognitive radio (CR) networks is formulated as maximizing the sum channel capacity while satisfying the power budgets of individual secondary user radios as well as the SINR constraints on both the ...

Dynamic Spectrum Sharing Models for Cognitive Radio Aided Ad Hoc Networks and Their Performance Analysis [PDF]
, 2011 In this paper, two dynamic spectrum sharing models are proposed, namely a Markov-chain model and a queue-based model in order, to evaluate the performance of CRAHNs, where the shared Primary Channels (PCs) are complemented by unshared Secondary Channels (

Modified Gini Index Detector for Cooperative Spectrum Sensing over Line-of-Sight Channels
Sensors, 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.
