Approximation and bound approaches for connection control in broadband satellite systems

Abstract

We develop a predictive connection admission control for broadband satellite networks. We apply the large deviation theory to a transient bufferless fluid model to develop connection admission rules. The algorithms are motivated by low computational capabilities and large propagation delay inherent in satellite communication systems. We develop the transient saturation probability and transient cell loss ratio as QoS measures. To find two QoS measures, we propose an exact fluid model, central limit theorem approximation, Chernoff bound and refined large deviation approximation. The numerical results suggest that the proposed bounding and approximation schemes are promising approaches for real time connection control.
