Title
Joint Optimization Of Qoe And Wasted Resources Due To Users Abandonment In Mobile Video Streaming
Abstract
Video traffic constitutes the majority of traffic in bytes that mobile and fixed line operators deliver to their customer. This type of traffic is both resource consuming and QoE sensitive. Either because of content quality or QoE, a large fraction of users often abandon viewing prematurely. These abandonment phenomena lead to a huge waste of network resources and device batteries. Several strategies have been devised to account for all those dimensions. Dominant approaches are fast-caching where the server pushes traffic as fast as possible to the client in order to limit starvation, and ON-OFF strategy where the client forces the server to pause the transfer regularly in order to mitigate the wasted bytes and energy due to users abandonment. In this work, we focus on fast-caching and on ON-OFF strategies. We develop an analytical model which takes into account users dynamics and allows us to quantify the loss in bytes due to users' viewing abandonment. Furthermore, we formulate a multi-objective optimization problem to find ON and OFF period durations that feature a good trade-off between loss due to abandonment and starvation probability.
