Abstract
This paper improves a previously proposed scheduling algorithm that is responsible to share the allocated capacity to the uplink traffic of an integrated satellite and WiMAX network. The target of this improvement is to schedule traffic of real time connections based on Quality of Experience (QoE) metrics. After a bibliographic search on QoE metrics, the FC-MDI (Frame Classification-Media Delivery Index) metric is chosen to be used in the proposed algorithm for the scheduling of real time connections. Two versions of the algorithm are proposed and evaluated. Simulation results show that the proposed algorithm considerably improves the QoE and the mean delay of the real time connections.
