Cognitive radio network (CRN) is designed to improve the low resource utilization problem caused by the fixed spectrum allocation policy used today. In CRNs, secondary users (SUs) sense spectrum holes and adaptively use the frequency band. In this paper, we tackle the Quality of Service (QoS) routing problem in wireless ad hoc CRNs. We consider such factors as available time, frequency bands, transmission...
Traffic driven based load balancing routing scheme in CogMesh network is proposed. SMC (secondary mesh client) accessing to CMR (cognitive mesh router) using Ad Hoc way is considered in the paper. A novel routing metric was proposed to describe the load state of a path, which was suitable for traffic demand. Choosing a light-loaded route and a light-loaded link guarantees a lower end-to-end delay...
