Abstract: The spectrum deficiency in cognitive radio can be solved effectively by utilisation of radio spectrum. The spectrum is not effectively shared among all the other users. Since the users are spread across different locations the spectrum allocation and spectrum sharing is important to use spectrum effectively and to allocate communication channel to all the devices in the network, by doing so all the nodes in the network can communicate covering large area. In cognitive radio, spectrum sensing, spectrum allocation, and reuse scenarios approaches with the different algorithm help improve the utilisation of the spectrum. Traditional spectrum allocation technique such as fuzzy logic and harmony search replaces the spectrum with the new spectrum scheme. However, the new technique brings more efficiency in achieving spectrum utilisation. Still the cognitive in mesh network has the problem of collision between the secondary and primary users. To minimise the effect of collision we introduce a gazer-based cognitive radio network (GCRN) which provides more freedom for frequency sharing paradigm. The novel algorithm provides the network to adopt automatically for every change in the environment of the cluster in cognitive radio network.
