摘　　要： 综合考虑激励因子、用户优先级和用户信誉提出一种基于社交网络的认知无线电频谱共享模型,并据此提出新的频谱共享方案。提出的方案通过对因子排序和比较各非授权用户的因子值,确定共享频带的非授权用户。结果表明,与未考虑社会关系的频谱共享方案相比,提出的频谱共享方案对应的成功共享次数更多,更能适应个性化的频谱共享环境。 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.
