Abstract (in Japanese) (See Japanese page) 
(in English) Various wireless communication systems are now being developed according to various users’ needs. For example, the 3rd generation mobile phone system has been explosively popularized worldwide, the coverage area of hot spot that encourages the diffusion of the mobile computing has been widely extended, and local connectivity technologies for ubiquitous networks are being realized. The authors have studied on “cognitive wireless access networks” in order to develop the networks that realize both high spectrum efficiency and high quality of service (QoS) for users. Cognitive wireless access networks can provide various communication routesd by adaptively aggregating or switching multiple wireless communication systems. In this paper, the hierarchical QoS route control scheme in cognitive wireless access networks is first explained and the definition of communication channel qualities required for the QoS route control is studied. The scheme of traffic distribution to multiple communication routes under multiple base stations is also discussed from the viewpoint of throughput maximization and the fundamental characteristics are examined from the experimental results with the cognitive wireless access network system that consists of IEEE802.16 and IEEE802.11b wireless devices.
