With the increasing popularity of cognitive radio networks (CRNs), providing data transmissions with quality of service (QoS) requirements in such networks becomes one of the most important topics. In this paper we study QoS provisioning in an ad hoc CRN with spectrum underlay. Both streaming traffic and non-real-time (nrt) data traffic are considered. The former requires a low session outage probability...
In this paper we study quality-of-service (QoS) provisioning in an ad hoc cognitive radio network with spectrum underlay. Both streaming traffic and non-real-time (nrt) data traffic are considered. An admission control scheme is first proposed based on relatively static information such as path loss and average interference levels in order to guarantee the average throughput of each connection. Outage...
