We present the motivation behind the proposal of the concept of cognition flow, provide the definition, discuss the features, behaviours, representations, mathematical models, and the functions of cognition flow in Cognitive Radio Networks(CRNs). We also analyse how the cognition flow promotes the convergence of heterogeneous networks.Our group also constructed the test platform to verify the usefulness of cognition flow. The results that were simulated by computers and tested on the platform both confirm that cognition flow can realise efficient interaction of cognitive information among heterogeneous networks in CRNs, which contributes to the seamless convergence of heterogeneous networks,and significantly improves the spectrum efficiency and users' Quality of Experience(QoE).展开更多
文摘在中国科学院'知识创新工程试点'工作的推动下,建设高水平研究基地,提高综合创新能力已成为大家的共识.2000年10月, 经科技部批准, 在中国科学院金属研究所原两个国家重点实验室和一个院重点实验室的基础上组建了'沈阳材料科学国家(联合)实验室(Shenyang National Laboratory for Materials Science, 以下简称SYNL)'.作为科技部和科学院基础研究基地建设改革的试点,SYNL在筹建和运行过程中得到了科技部和科学院的大力支持,同时围绕国家实验室的建设目标,在学科建设、人才引进、运行机制等方面进行了新的探索和尝试.
