Abstract
The paper presents a novel approach for dynamic bandwidth allocation (DBA) in GEO satellite networks based on adaptive predictive control. In the proposed DBA scheme each satellite gateway (SG) uses an adaptive predictor to forecast the future input traffic flow along with a bandwidth controller to generate a bandwidth request to the bandwidth manager (BM) according to a receding-horizon policy, via solution of an optimal control problem. A multi-service traffic scenario is considered with a careful eye to guarantee differentiated quality of service requirements. Simulation experiments demonstrate that the predictive DBA technique proposed in this work outperforms fixed allocation as well as existing reactive DBA methods.
