Abstract: Cognitive wireless single hop network rate control model on Stackelberg game is proposed. By applying the backward induction to analyse the Nash equilibrium, the existence and uniqueness of the proposed model’s Nash equilibrium are proved, and the Nash equilibrium’s specific expression of the Stackelberg game model is given. Simulation validates the correctness of the proposed model, simulation results show the utility is optimal at the Nash equilibrium point, and the cognitive user can achieve the optimal date rate on the Nash equilibrium point.

摘要： 提出了基于Stackelberg博弈的认知无线单跳网络流量速率控制模型。应用反向归纳法对提出的流量速率Stackelberg博弈模型纳什均衡进行了分析，证明了提出的模型纳什均衡存在性及唯一性，并给出了Stackelberg博弈模型纳什均衡解的具体形式。仿真验证了提出的模型正确性，仿真结果表明在模型的纳什均衡处网络总体效用是最优的，且网络效用最大时认知结点可获得最优数据传输速率。
