A QoE-Aware Scheduler for HTTP Progressive Video in OFDMA Systems

摘要: HTTP progressive video downloading is becoming increasingly relevant in wireless and mobile networks. Therefore, improving the quality of experience (QoE) for this service important customer satisfaction. In letter we propose a QoE-aware scheduling solution OFDMA systems. Whereas most strategies consider QoS metrics such as delay, jitter or throughput, our proposal takes into account metric that directly affects end-users experience. particular, to use an estimation amount data stored player buffer main criterion resource assignment. The ultimate goal using avoidance playback interruptions. have evaluated scheduler LTE network simulator YouTube service, which visited streaming site. Our results show significant improvement compared Multicarrier Proportional Fair scheduler, e.g. number videos with pauses decrease from 16.1% 0% 12 Mbps cell offered load.
