Analysis of parameters for improving Efficiency on Cognitive Cooperative Network

Cognitive radio (CR) on the SDN uses the signal processing mechanism to sense the available spectrum to be utilized on the different layers of the network. The cooperative framework builds and communicates in such a way relay transmission is used through multiple-path propagation of nodes in the network. To deploy both cognitive and cooperative communication on a network with the changing environment and limited resources become a challenging task for bringing up an efficient network. The relaying of messages through the spectrum channels creates a large opportunity in bandwidth frequency and diversity attainment. The parameters like queuing of the relay nodes, reducing the delay between the communicating nodes and increasing throughput involved with the usage of the spectrum available with primary users (PU) used by secondary users (SU) becomes a big challenge in QOS for producing an effective cognitive cooperative network.
