Improvement in Utilization of the Spectrum using Cognitive Radio nodes

Currently, the research towards spectrum management has been increased inorder to avoid the scarcity of the spectrum and to improve the utilization of the spectrum which shows that researchers concentration towards spectrum utilization also get increased. This paper provides how ways of spectrum utilization and implementation varies from researchers to researchers. The main objective of the paper is to improve the overall spectral efficiency by sharing the spectrum among the service providers and avoiding the spectrum scarcity. The proposed system validates the utilization of spectrum sharing in three different ways like Normal utilization, applying Fuzzy logic system and predicting traffic pattern and finally proves that utilization of the spectrum has been improved with reduced call blockage, reduced interference and reduced high traffic patterns of the calls. This paper also gives the study of Spectrum sharing with different technologies. KeywordsCall Blockage, Primary User, Call Holding, Spectrum Sharing, Traffic Pattern
