Abstract: Resource allocation is one of the most important issue in network planning especially in wireless communication, Cognitive radio system is a technology where secondary user looks for a free band to use when primary user is not in use of its licensed band. A function of cognitive radio is called Spectrum sensing which enables to search for the free bands and it helps to detect the spectrum hole (frequency band which is free enough to be used) which can be utilized by secondary user with high spectral resolution capability. This paper aim to enhance dynamic channel allocation through cognitive radio technology MATLAB has been used to evaluate the performance of cognitive radio network to get optimal dynamic channel allocation.
