Study on Inter-Base Station Link Capacity Sharing using Cognitive Radio Communication

This paper describes a study on beam switching scheme applicable to the cognitive radio communication, from the viewpoint of the efficient use of radio frequency resource, as a function of the response time of Web browsing. The beam switching is time division scheme of the assigned frequency bandwidth among one wireless link and another links. Regarding the radio network, we consider three types of topology. As a result of software simulations, we conclude that the radio beam switching have the better performance in frequency use, comparing with the case of the conventional fixed frequency allocation. Furthermore, we simulate the IP throughput characteristics and response time characteristics of Web browsing in the radio link affected by transmission error.
