A network is an interconnection of different users where different users exchange information with each other using transmitters and receivers. When the information is needed to be transmitted automatically then in such cases cognitive radio network is used. The transmitters in the cognitive networks are signaled such that they can automatically detect the available channels and pass signals through them. In such a situation availability of channels plays the important role. As channels are generally limited so they need to be shared among the participating users.
