多业务驱动的多跳认知网络智慧路由及适变传输机理研究

With the development of multi-hop Cognitive Radio Network (CRN), its services are increasingly rich and diverse and the perspective of its application is promising.The task of designing intelligent routing and adaptive transport schemes are challenging in the multi-hop CRN research..Our project starts from the diversified service needs of CRN, combines the theory and research of economics,sociology and information science. The start point of the project is to maximize the utilization of spectrum opportunity to satisfy the needs of secondary users in the mobile communications. Based on the full consideration of dynamic spectrum availability in multi-hop cognitive radio networks and diverse service needs, the research focuses on their influence upon the network topology and transport quality of service and the related new problem,proposes the intelligent routing protocol and adaptive transport scheme for the multi-hop CRN and ultimately attains the goal of improving the resource utilization efficiency and quality of the network service of the whole network in multi-hop CRN.
