METHOD OF CONTROLLING CONNECTOIN ADMISSION IN COGNITIVE RADIO NETWORKS

摘要

PURPOSE: A method of controlling connection admission in a cognitive radio network is provided to supply a more qualified service to a first user who acquires a license as well as a second user who does not acquire the license. CONSTITUTION: If there is a channel in which probability for the appearance of a first user is lower than a first threshold value(S13), the estimation value of the maximum channel number used during the use time requested by the second user is calculated(S15). The estimation value of the calculated maximum number of channels is compared with the second threshold value. When the estimation value is lower than the second threshold value(S16), the connection to the second user is approved(S17). When the estimation value exceeds the second threshold value, the connection to the second user is denied.
