Abstract

This paper presents Model on optimizing primary spectrum allocation using cognitive radio. A theoretic dynamic spectrum access algorithm that improves upon on a hedonic coalition formation algorithm for spectrum sensing and access for frequency modulation radio spectrum is presented. The modified algorithm is tailored to eliminate interference, faster convergence and makes use of a simultaneous multi-channel sensing and access technique. Results to demonstrate the performance improvements of the adapted algorithm are presented and the use of different decision rules are investigated revealing that primary spectrum can be used without interference with the secondary user. The algorithm that was developed could be a key for prospect primary spectrum networks to be used.
