Abstract :
The enormous development in Wireless Communications has added to an immense request on the sending of new remote administrations and their applications prompts range shortage in both licensed and unlicensed frequency spectrum. Cognitive Radio Technology is utilized to get to the inaccessible range proficiently by designating the range to the unlicensed clients i.e. Secondary Users (SU) when it is not utilized by the licensed users i.e. Primary Users (PU). Be that as it may, the system is defenseless against new sorts of security dangers because of the circulated idea of helpful range detecting. The present range does not give security system to alleviate against these attacks. This proposed framework researches different attacks and security component for the future upgrading in Cognitive Radio Sensor Networks (CRSN).
