dc.description.abstractThis paper presents an adaptive algorithm for man-aging the weight values of the Weighted Round Robin (WRR)scheduler to provide End-to-End (E2E) Quality of Service (QoS)guarantees for Broadband satellite systems. The weight calcu-lation depends on the capacity variations present in the DigitalVideo Broadcasting-Second Generation (DVB-S2) satellite link.The algorithm is defined to optimize the bandwidth utilizationwhile satisfying the QoS requirements for different traffic classes.The operation of the proposed algorithm is demonstrated usingthe NS-2 simulator tool. The results show that the proposedadaptive WRR algorithm optimizes the bandwidth utilizationwhile enforces the priority level of each service class whenan extreme reduction of bandwidth caused by rain events isexperienced in the satellite system.
