摘要 提出一种适用于认知网络的认知差错控制策略(CEC),该策略根据认知数据帧被转发所经历的跳数和类型的重要性智能地为丢失数据帧选择最佳差错控制机制来改善认知网络的通信性能。建立了认知网络能效模型,数学分析和仿真比较表明:该策略能够有效地提高认知网络多媒体数据传输的可靠性,同时保持高能效。 A cognitive error control mechanism for cognitive networks,called CEC was proposed.CEC was based on the cognition of importance of data frames’ hops and types,which could select a best error control mechanism to improve the communication performance in cognitive networks.Besides,the energy efficiency model of cognitive networks was built.The mathematical analysis and simulation comparisons show that the proposed CEC mechanism achieves better per-formance in terms of communication reliability and energy efficiency in cognitive networks.
