Abstract
With the rapid development of digital communication, the demand for spectral resources is increasing and the building of cognitive radios is the right solution for that. Cognitive radio networks are designed to utilize the licensed spectrum when it is not used by the primary licensed users. We are going to propose a method for effective data transmission and streaming in cognitive radio networks. By that we can achieve energy efficiency, less power consumption and much more transmitted information. In this paper, we are going to employ the OFDM method of spectrum sensing and proposed to use Cognitive Radio MAC protocol. Further our main technique is to divide the data packets into different sizes for transmission. The simulation results reveal that there is a better improvement in the detection of idle channel in the cognitive radio network and the delay is reduced with high quality transmission.
