Cognitive radio plays a vital role and can be taken as a feasible alternative in future for mobile communication networks. Spectrum allocation will become a serious issue in cognitive radio networks if it is not addressed. In this research we are proposing an enhanced structural mobility model for cognitive radio network. We express a distinctive spectrum reallocation algorithm based on mobility model that incorporates secondary user’s (SU) mobility. In part, simulation findings confirm that spectrum reallocation algorithm has a good system communication overhead performance.
