To have a successful communication in Ad Hoc networks, Cognitive Radio (CR) can funding a flexible utilization of wireless radio spectrums. Routing Protocol is a significant problem in CRNs. Some routing protocol is based on different scenarios and it should incorporate QoS parameters in route definition to support QoS performance. Some revisions are done to the Cognitive Radio Ad Hoc network (CRAHN)...
A routing protocol, in Cognitive Radio Network (CRN), is a new concept to improve performance in this network. It is used to establish correct and efficient route between two nodes. OLSR (Optimized Link State Routing) protocol is an optimization of the classical link state protocol in Ad Hoc Networks. We introduce the QoS (Quality of Service) routing mechanism for OLSR protocol, QOLSR (QoS OLSR)....
