Non-cooperative game theory based cognitive wireless network spectrum resource optimal distribution method

The invention discloses a non-cooperative game theory based cognitive wireless network spectrum resource optimal distribution method. Firstly, an authorized user counts a number of idle spectrums based on a use condition thereof and prices the spectrums; then the authorized user sends spectrum pricing information to each cognitive user; cognitive users obtain use permission of the spectrums aftera non-cooperative game based on demands per se and a current spectrum price; and finally, each cognitive user delivers the best demanded spectrum number to the authorized user, and the authorized userdistributes the spectrums to the cognitive users according to the applied spectrum number so as to finish the spectrum distribution process. Compared with other similar technologies, the non-cooperative game theory based cognitive wireless network spectrum resource optimal distribution method has the characteristics of simple steps, convenient calculation and fast convergence. 本发明公开种基于非合作博弈论的认知无线网络频谱资源优化分配方法，首先由授权用户根据自身的使
