A game algorithm of dynamic spectrum allocation based on spectrum difference

Game theory-based cognitive radio dynamic spectrum allocation, is one of the hot researches of the field of cognitive radio. Taking into account the differences in the spectrum, using a Cournot game model, and adding the spectral similarity matrix to the original pricing function, a new utility function that makes the spectrum allocation more close to the actual network environment is proposed. Simulation analysis shows that, the allocation algorithm considering the differences in the spectrum is more diverse than the original algorithm, and is suitable for the allocation of the actual network.
