Abstract:
This paper investigates the traffic capacity and the quality of service provisioning in cognitive radio networks used as secondary networks for dynamic spectrum access in accordance with the hierarchical spectrum overlay approach. An analytical model for cross-layer performance analysis of secondary cognitive radio networks is developed. New performance measures for the interference experienced by the primary and the secondary users are proposed. A novel approach for evaluation of the call dropping probability of the secondary users is suggested.
