The spectrum mobility during data transmission is an integral part of the cognitive radio network (CRN) which is conventionally two types for instance reactive and proactive. In the reactive approach, the cognitive user (CU) switches its communication after the emergence of the primary user (PU), where the detection of emergence of PU relies either on spectrum sensing and/or monitoring. Due to certain...
Due to the explosive growth of wireless services with high-speed and better quality-of-services, the demand of spectrum is increasing proportionally. In addition to this, the fixed spectrum allocation scheme of the desired radio frequency bands also creates the spectrum scarcity problem. However, the possible solution of these problems is the cognitive radio (CR) communication technology, which is...
