Cognitive Radio Mobility Based Routing Protocol for CR enabled Mobile Ad Hoc Networks

This paper proposes a cross layer routing protocol called CRMBR (Cognitive Radio Mobility Based Routing Protocol.), which operates with Cognitive Radio (CR) Mobile Ad Hoc Networks. In the near future, with the rapid development of hardware and chipset functionality, devices with CR capability will offer promising opportunities within future mobile networks. The new routing protocol exploits the transfer of CR performance data from the Physical/MAC layers up to Network layer as contributing factors within the route selection algorithm. A newly defined node mobility factor is considered together with the physical layer sub-channel real-time conditions when the route needs to be selected. The performance of the proposed scheme is investigated via simulations and the results confirm its favorable operation within CR MANET environments compared to AODV and DSR.
