Abstract

An attempt has been made to analyze the spectrum utilization across different cellular i.e. GSM, CDMA, UMTS and WiMAX under realistic traffic scenario. The presented simulation study in this paper shows that on an average around 60% of the spectrum remains unutilized for duration of 24 hr. The Dynamic Spectrum Allocation (DSA) approach optimized by Genetic Algorithm (GA) has been applied to enhance spectrum utilization based on concept of Cognitive Radio. The feasibility study for enhanced spectrum utilization across different cellular technologies considering present regulations have been simulated and results are presented in this paper.
