Abstract
This paper proposes an improved QoS scheduling scheme, called the Modified Proportional Fairness with MultiHop (MPF-MH) algorithm for Cognitive Radio Mobile Ad Hoc Networks (CR MANET). Within the context of multi-channel MAC enabled networks, mobile nodes can experience simultaneous transmission across multiple channels. Benefiting from the proposed cross layer design, the real-time channel conditions provided by CR function permits adaptive subchannel selection for each transmission. MPF-MH adaptively schedules the radio resources for serving different types of service in order to optimize network resources without decreasing the quality of service. Simulation results confirm that MPF-MH provides good QoS guaranteed performance across a variety of CR MANET scenarios.
