Performance-driven adaptive admission control for multimedia applications

In this paper we study an adaptive measurement-based admission control scheme that is suitable for multimedia applications with diversified QoS requirements. The conservativeness of the proposed admission control scheme is self-adjusted based on the measured QoS performance of the existing multimedia flows. Extensive simulations performed on actual multimedia traffic with different combinations of traffic patterns, QoS requirements, and flow lifetimes have shown that the proposed scheme effectively balances the trade-off between high utilization and reliable QoS under different network conditions, hence enables a significant utilization increase compared with existing measurement-based admission control schemes.
