摘要：A network is an interconnection of different users where different users exchange information with each other using transmitters and receivers. When the information are need 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 [1]. 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. The users who own channels of their own are named as Licensed Users (LU), and those does not own channels of their own, need to use channels owned by the licensed users are called Unlicensed users (UU). The existing system tells about the contents of information circulated in the network while the proposed system is all about transferring and gathering information in the network. The cells undergo a game called groups formation where they switch from one group to another in search of available channels.
