Abstract:
Spectrum is a scarce resource. The cognitive radio environments utilize the spectrum efficiently through the dynamic spectrum access approach. Game theory, genetic algorithms, neural network, marketing, and economic models became the catalysts to boost the dynamic spectrum access for efficient utilization of the spectrum. Combinations of these models may sometimes help better in the allocation of unused spectrum (spectrum holes) for cognitive users (secondary users). The paper introduced the electronic commerce model to identify a quality channel preferred by the secondary user. The rating of the spectrum (channel) was modeled with a combination of Sporas formula and fuzzy reputation model proposed by Carbo, Molina and Davila. The proposed model helps to select the quality channel to cognitive user. Further, the cooperative game theory was introduced to gain the better channel by the cognitive user. The channel selection also tested with automated collaborative filtering and case-based reason applications.
