Abstract
Provided is a device for allocating a dynamic frequency for a secondary user in a cognitive radio network. The device includes: an OP map generation unit for generating an opportunity map, which represents a probability of successful communication of the secondary transmitter in each region of the cognitive radio network, by using one or more of spectrum sensing information, which is received from a spectrum sensor that has completed sensing and includes identifier information, location information, and a sensing measurement matrix, an access request message, which is received from the secondary transmitter and includes identifier information, location information, and operable band information, and the density and transmission powers of primary transmitters; and a response message generation unit for generating a response message, which includes the channel having the highest probability of successful communication and the probability of successful communication, based on the generated map.
