For session-level quality-of-service (QoS) provisioning in cognitive radio networks (CRNs), it is essential to adopt an effective admission control scheme with appropriate parameters. In this paper, a framework for admission control and session-level performance analysis is proposed by taking into account several factors such as channel reservation for handoff secondary users (SUs), buffers for handoff...
In this paper, a low-cost channel reservation design scheme is proposed for cognitive radio networks (CRNs) to achieve call level quality of service (QoS) provisioning. An optimization problem is formed to minimize the handoff call dropping probability with a hard constraint on the new call blocking probability, and then is rewritten to another problem where only the new call blocking probability...
