A Routing Protocol for Enhanced Efficiency in Cognitive Radio Networks

This paper proposes a novel routing protocol enriched with an assigning mechanism that enables for efficient data flow coordination, among communication nodes with heterogeneous spectrum availability in distributed cognitive radio networks. Efficient routing protocol operation, as a matter of maximum-possible routing paths establishments and minimum delays is obtained, by utilizing a signaling mechanism that was developed based on a simulation scenario. This simulation scenario includes a number of secondary communication nodes, operating over TVWS (television white spaces) under the "spectrum of commons" regulation regime. The validity of the proposed routing protocol for enhanced efficiency in cognitive radio networks is validated, by conducting experimental simulations and obtaining performance evaluation results. Simulation results verified the efficiency of the proposed routing protocol for minimizing routing delays among secondary communication nodes and indentified fields for further research.
