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 improved in order
to be used in two proposed alternative algorithms for the scheduling of real time
connections. Simulation results show that the proposed algorithms, especially
the one with rate adaptation, considerably improve the QoE and the mean delay
of real-time connections.
Keywords
