Priority Based Spectrum Sensing and Security System using Radio Cognitive Network

Today increasing demand for the radio spectrum access due to many new wireless networks such Bluetooth, share it and so on. The radio spectrum is the part of the Electromagnetic spectrum with frequencies from 3 KHz to 300 GHz and these are generally used in Telecommunication. Existing method tells that in a Cognitive Radio network, secondary users can access unused licensed spectrum bands. The Collaborative spectrum sensing has been used for the sensing reports from Secondary User's are sent to one or more decision making authorities to produce more reliable decisions on the spectrum usage. However, in the presence of misbehaving or malicious secondary users, the integrity of the reports sent by SUs needs to be assessed to avoid interference with Primary User's. Our proposed is an efficiently accessing the spectrum sharing among primary users and secondary users. In this project, they consider a cognitive radio with the primary and secondary links. By using Cognitive Radio, the unlicensed spectrum uses the licensed channel for data transmission. The proposed Channel Side Information at the cognitive radio network is generally used to maintain which primary user channels are ideal and arranged them in a priority based queue. The proposed system uses the Spectrum Sharing algorithm which calculates the load of the information which transfers. It provides a power minimization allocation approach, low power consumption. Result show that the both spectrum sensing and data transmission/receiving functions.
