Abstract

Cognitive radio (CR) is a new technology in wireless communications. Presently, we are facing spectrum scarcity problem. CR gives solution to spectrum scarcity problem. The idea behind cognitive radio is the utilization of unused frequency bands of primary or licensed users (PU) by secondary or unlicensed users (SU). This unused frequency band is called white spaces or spectrum hole. This scenario needs the demand of cognitive radio. Spectrum sensing is the main task in CR. Proposed system has used energy detection method for spectrum sensing by using new threshold formulations. Novel algorithm for optimized handoff decision using fuzzy logic and artificial neural network and proactive strategy is used for channel allocation. The proposed system saves the power and optimized handoff delay.
