A Contract-Based Spectrum Trading Scheme for Cognitive Radio Networks Enabling Hybrid Access
IEEE Access, 2015 The latest trends in spectrum trading allow secondary users (SUs) to employ hybrid access models and exploit bandwidth employing either opportunistic spectrum access or exclusive spectrum access of vacant frequency bands (FBs) leased for exclusive usage.

Suboptimal Approach to Distributed Detection in Cognitive Radio Networks
Journal of Telecommunications and Information Technology, 2021 In this paper a dynamic spectrum access (DSA) concept is explored for mitigating the paucity of spectral bandwidth in cognitive radio (CR) for opportunistic, dynamic access of the spectrum without any interference.

Revenue Maximization in Spectrum Auction for Dynamic Spectrum Access
Proceedings of the 5th International ICST Conference on Performance Evaluation Methodologies and Tools, 2011 We investigate revenue maximization problems in auctions for dynamic spectrum access. We consider the frequency division and spread spectrum methods of dynamic spectrum sharing. In the frequency division method, a primary spectrum user allocates portions of spectrum to different secondary users. In the spread spectrum method, the primary user allocates

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 ...

The SS-SCR Scheme for Dynamic Spectrum Access
Journal of Computer Networks and Communications, 2012 We integrate the two models of Cognitive Radio (CR), namely, the conventional Sense-and-Scavenge (SS) Model and Symbiotic Cooperative Relaying (SCR). The resultant scheme, called SS-SCR, improves the efficiency of spectrum usage and reliability of the ...
