Second international workshop on modeling, measurements and optimization of video performance over w

Video services are witnessing a rapid growth in mobile networks. In this context, HTTP streaming services (Youtube-like) are the most represented video services, but real-time streaming and mobile TV are gaining in importance. The large variability of the wireless channel due to fast fading, users’ mobility and to the flow level dynamics of users makes the delivery of video services over mobile network a challenging task. Although continuity in video delivery is the main measure for Quality of Experience (QoE) for video users, the detailed QoS measures depend on the specificities of each video service. For instance, while congestion periods lead to re-buffering for http streaming services (the video restarts after the congestion), the contents that are not delivered during the congestion period are definitely lost for real-time streaming and mobile TV. The aim of this workshop is to propose and analyze solutions that enhance the performance of video delivery over wireless networks, from users’ point of view (QoS/QoE), but also from the network side (capacity and energy efficiency).
