| 为了提高频谱共享的有效性和公平性，提出了一个基于合作博弈的认知网络频谱共享
模型和接入控制策略。博弈规则为在满足各用户最小收益的前提下，认知用户进行相互合作
，并最大化总体收益；接入控制策略以满足服务质量需求为约束条件，并引入惩罚函数，迫
使认知用户按照其实际需求竞争频谱资源。仿真结果表明：提出的合作博弈模型和接入策略
提高了认知用户的总体收益和公平性，改善了系统中认知用户的满意度。 |

| Abstract: |
| In order to improve the efficiency and fairness of spectrum sharing, a
spectrum sharing model based on cooperative game and an access control policy a
re proposed. Cognitive users cooperate with each other to maximize overall ben
efits on the premise of meeting users′ minimum income. The access control polic
y takes the satisfaction of service quality requirements as the constraint condi
tion. A penalty function is introduced to force the secondary users to compete s
pectrum according to their actual requirements. The simulation results show that
the cooperative game model and the access policy proposed in this paper enhanc
e the overall benefits and fairness of cognitive users and improve the cognitive
users′ satisfaction in the system. |
