Improved rtPS SchedulingwithQoE metrics in Joint WiMAX / Satellite Networks
Journal Title: International Journal of P2P Network Trends and Technology(IJPTT) - Year 2012, Vol 2, Issue 1
Abstract
Thispaper 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 twoproposed 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
