摘要
综述了近年来在认知无线电网络中用户行为建模的相关研究成果,第1部分主要论述了认知无线电网络中授权用户行为建模的相关方法及其模型,第2部分论述了认知无线电网络中认知用户行为建模的相关方法及其模型。提出未来的主要研究方向是研究授权用户行为、频谱空隙模式、认知用户行为、用户流特性这四者之间的内在联系及其相互之间的约束关系,揭示它们之间的本质联系。
This paper surveys the relevant achievements in the research on users＇ behavior modeling in cognitive radio networks in recent years. The first part discusses the relevant methods and model of primary users＇ behavior modeling in the cognitive radio network ; the second part discusses the relevant methods and model of secondary users - behavior modeling in the cognitive radio. The paper proposes that the future research direction is the internal relationship among primary user behavior, spectrum interspace mode, cognitive user behavior, and user flow characteristics and their restrictive interrelation, and it reveals their essential relationship.
