QoE-based packet drop control for 3D-video streaming over wireless networks

Abstract

Currently, the Internet is experiencing a revolution in the provisioning and demand of multimedia services. In this context, 3D-video is envisioned to attract more and more the multimedia market with the perspective for enhanced applications (video surveillance, mission critical control, entertainment, etc.). However, 3D-video content delivery places increased bandwidth demands, as well as have rigorous Quality of Service (QoS) and Quality of Experience (QoE) requirements for efficient support. This paper proposes a novel QoE-aware packet controller mechanism, which aims at connecting real-time 3D-video streaming applications over congested wireless networks with acceptable levels of QoS and QoE over the time. Simulation experiments were carried out to show the impact and benefit of our proposal. Subjective and objective QoE metrics were used for benchmarking, showing that in congestion periods our solution improves the quality level of real-time 3D-video sequences from the user point-of-view, as well as, optimizes the usage of wireless network resources.
