Cognitive QoS-on demand routing protocol (CO-QORP) in cognitive radio Ad-hoc network

Cognitive Radio (CR) presents a new approach to wireless spectrum utilization. A big number of Routing Protocols for Cognitive Radio Ad Hoc Networks (CRAHNs) have been proposed to increase the efficiency of spectrum utilization. These protocols don't maintain the QoS mechanisms. Many revisions are done to the CRAHN protocols to meet QoS challenges focused on bandwidth, end to end delay, total packets dropped. So, we propose to develop and implement a new algorithm CO-QORP (Cognitive QoS On demand Routing Protocol) that integrates the QoS adaption mechanism in Cognitive On demand Routing Protocol. From the simulation results, it is observed that the CO-QORP provides better performance. Numerical simulations validate the proposed protocol (OPNET 14.5).
