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, the queue dynamics of secondary users (SUs) in a multi-SU and multi-channel cognitive radio network is analyzed to obtain the expressions of quality of service (QoS) metrics. Specially, in the analysis, we take several lower-layer mechanisms and settings into account, including automatic repeat request (ARQ), finite-size buffer, adaptive modulation and coding (AMC) and non-ignorable...
