Spectrum allocation of cognitive radio system based on SFOA
Xiang Xiangqi · Computer Engineering and Applications Journal · 2014
This paper proposes a novel spectrum allocation method of cognitive radio based on Optimization Algorithm on Simulating the Fisher Fishing(SFOA)to solve the spectrum allocation problem of cognitive radio system. Spectrum allocation optimization mathematical model of the cognitive radio is established whose maximum benefit is taken as the optimization goal, and then the optimal spectrum allocation scheme is obtained by SFOA which has less parameters,encodes easily, strong ability. The simulation experiment is carried out to test the performance of SFOA algorithm. The results show that the proposed method not only increases users mean system utility, but also improves the efficiency of spectrum allocation.
