摘要: 动态频谱管理技术是认知无线网络技术的重要组成，是设计高效的认知无线网络系统架构、实现动态频谱感知、动态频谱接入等的关键技术。对基于势博弈的认知无线网络动态频谱管理研究，分析了博弈论与动态频谱管理之间的映射关系。基于势博弈，对认知无线网络动态频谱管理进行了建模，给出了主要管理过程。对提出的模型进行了仿真实验，结果显示通过基于博弈论的方式来描述认知无线网络各个用户间的行为，不仅能够研究各个节点的个体行为，同时还能够指导认知无线网络动态频谱分配、节点认知方式设计等。

Abstract: Dynamic spectrum management is one of the important components in cognitive radio, which can build ef- fective system structures for cognitive radio network in order to realize the dynamic perception and access of spectrum. This paper explores dynamic spectrum management technologies based on potential game theory. It firstly analyzes the mapping relationship between game theory and dynamic spectrum management. Then, the model of dynamic spectrum management is established in cognitive radio network by potential game and the main process is given. The simulation is carried out and the results show that the presented model cannot only describe user behaviors in cognitive radio net- work, but also assist the design for dynamic spectrum allocation.
