A Dynamic Cluster Based Architecture for Cognitive Radio Networks

چکیده
To encounter the emergent necessity of radio spectrum, which is a limited natural resource, proper utilization of the radio spectrum is a must. Introduction of cognitive radio networks can play a vital role to solve the spectrum scarcity. Cognitive radio uses an open spectrum allocation technique to make more efficient utilization of the wireless radio spectrum and reduce the bottleneck on the frequency bands. To deploy Cognitive Radio, a robust architecture is preconditioned. A dynamic cluster-based architecture is proposed for cognitive radio network in this paper. The proposed architecture breaks the Ad-hoc architecture of cognitive radio network into cluster for load balancing and efficient routing. The communication protocols for the proposed architect are ease to deploy so that it can be used for communication in natural calamities such as tsunami, earthquake, etc. Keywords— Cognitive radio network, network architecture, cluster networks, communication protocol
