Matching Theory for Channel Allocation in Cognitive Radio Networks

Efficient Channel Allocation Schemes for Cognitive Radio Networks

In today’s wireless scenario, most of the spectrums (licensed bands) are already allocated for license users for exclusive use. Few unlicensed bands are left open for unlicensed users, i.e. ISM bands 900MHz and 2.4GHz. Licensed bands are under-utilized but unlicensed bands are crowded resulting on spectrum scarcity. Solution is to let unlicensed users use the license frequencies, provided they ...

Matching-based Spectrum Allocation in Cognitive Radio Networks

In this paper, a novel spectrum association approach for cognitive radio networks (CRNs) is proposed. Based on a measure of both inference and confidence as well as on a measure of qualityof-service, the association between secondary users (SUs) in the network and frequency bands licensed to primary users (PUs) is investigated. The problem is formulated as a matching game between SUs and PUs. I...

Asynchronous Channel Allocation in Opportunistic Cognitive Radio Networks

In the case of Opportunistic Spectrum Access (OSA), unlicensed secondary users have only limited knowledge of channel parameters or other users’ information. Spectral opportunities are asymmetric due to time and space varying channels. Owing to this inherent asymmetry and uncertainty of traffic patterns, secondary users can have trouble detecting properly the real usability of unoccupied channe...

Spectrum Allocation Based on Game Theory in Cognitive Radio Networks

As a kind of intelligent communication technology, the characteristic of dynamic spectrum allocation of cognitive radio provides feasible scheme for sharing with the spectrum resources among the primary user and secondary users, which solves the current spectrum resource scarcity problem. In this paper, we comprehensively explored the cognitive radio spectrum allocation models based on game the...
