Abstract :
The agile evolution of wireless technology has caused the slenderness of spectral bandwidth. Federal Communication Commission of US narrated that 70% of available spectrum is not utilized efficiently. In cognitive radio wireless communication, the transceiver intelligently scans the spectrum and occupies any vacant channel. Due to this scarcity of spectrum, new techniques are being analyzed for optimal bandwidth utilization. This paper introduces an optimal scheme for allocating the spectrum in centralized intra networks. The algorithms have been thoroughly studied and the one optimum in terms of fairness and throughput is selected. The simulation of these algorithms is done in MATLAB.
