The increasing popularity of video (ie, audio-visual) applications or services over both wired
and wireless links has prompted recent growing interests in the investigations of quality of …

Our purpose in this paper is to characterize buffer starvations for streaming services. The
buffer is modeled as a FIFO queue with exponential service time and Poisson arrivals. When …

Video streaming service in wireless networks is increasingly using dynamic selection of
video bit-rates to provide a high quality of user experience (QoE). The bit-rate switching …

Bandwidth cost is a significant concern for online video service providers. Today's video
streaming systems mostly use HTTP streaming, with users accessing video segments as …

As video accounts for larger wireless traffic, improving users' quality of experience becomes
important for network service providers. In this paper, we apply supervised machine learning …

Unraveling quality of experience (QoE) of video streaming is very challenging in bandwidth
shared wireless networks. It is unclear how QoE metrics such as starvation probability and …

This paper proposes online scheduling policies to optimize quality of experience (QoE) for
video-on-demand applications in wireless networks. We consider wireless systems, where …

Energy efficiency and Quality of Service (QoS) are two important considerations for the
design and planning of cellular networks. One effective approach to handle the tradeoff …

In regard to the continuing network densification as a part of the solution to the mobile data
traffic demand explosion, managing future 5G ultra-dense networks is becoming …

Video streaming is anticipated to dominate wireless traffic in the near future. We study
wireless systems where an access point delivers video streams to multiple clients over …
