在异构多认知无线网络共存场景中,资源配置是共存协调的关键之一.构建了一种基于线性价格机制的多认知无线网络资源配置框架:将用户带宽需求差异用信道传输特性描述,运用线性价格函数表征认知用户效用和认知无线网络收益,将资源配置抽象为博弈模型,包括三阶段动态博弈:第一阶段,认知无线网络确定向主无线网络租用带宽;第二阶段,认知无线网络确定认知用户使用带宽单价;第三阶段,认知用户通过比较接入不同网络时自身效用,选择能最大化效用的网络接入.阐述了该动态博弈纳什均衡存在的条件和均衡点特性,仿真验证了该框架的合理性和有效性.
In the co-existence scene of heterogeneous multi-cognitive radio networks, resource allocation is one of the keys to coexistence and coordination.A multi-cognitive radio network resource configuration framework based on linear pricing mechanism is constructed: the difference in user bandwidth requirements is described by channel transmission characteristics , The linear price function is used to characterize the cognitive user utility and the cognitive wireless network revenue. The resource allocation is abstracted as a game model, including three-stage dynamic game: In the first stage, cognitive wireless network determines the bandwidth leased to the main wireless network. In the second stage , Cognitive radio network to determine the cognitive users to use the bandwidth unit price; the third stage, cognitive users through access to different networks compare their own utility, choose to maximize the effectiveness of the network access.Expans the dynamic game Nash equilibrium existing conditions And equilibrium point characteristics, the simulation verifies the rationality and effectiveness of the framework.
