Cognitive radio spectrum sharing model based on social networks
基于社交网络的认知无线电频谱共享模型*

This paper proposed a cognitive radio spectrum sharing model based on social networks by jointly considering the incentive factor, user priority and user credit.And formulated a new spectrum sharing scheme. The proposed scheme determined the unlicensed user that could share the spectrum band through sorting the factors and comparing the values of the factors of the unlicensed users. The results show that compared with the spectrum sharing scheme without considering social relationships, the proposed spectrum sharing scheme brings more successful spectrum sharing chances and is more suitable for personalized spectrum sharing environments.
