英文摘要： With the combination of the distributed cooperation technology and intelligent cognition technology, a new technological approach for distributed wireless networks will be explored in this project to provide effective interconnection among distributed nodes. Based on the universal description of quality of service, the model, which portrays the cooperative and competitive actions of group nodes with different identities in distributed wireless networks, will be constructed. Moreover, to seek the new methods which improve the distributed wireless networks' performance by utilize the smart group behaviors, the different ability of different cooperative cognitive strategies to guarantee QoS is investigated. Ultimately, it will be implemented into cooperative cognitive multiple access protocol design so as to provide high-quality services to various nodes and traffics. The achievements will provide necessary theoretical and technical supports for the new generation distributed wireless network.
