A NOVEL COORDINATED ADAPTIVE VIDEO STREAMING FRAMEWORK FOR SCALABLE VIDEO OVER MOBILE NETWORKS

This paper presents a novel adaptive video streaming framework designed for OFDM-based mobile networks. The proposed adaptation algorithm exploits the benefits of the Scalable Video Coding (SVC) extension of the H.264/AVC standard together with cross-layer information from the mobile terminals in performing adaptation that maximizes streaming qualities amongst all participating users. Simulations for adaptive video streaming along with the well-known TFRC-based and no adaptation scenarios were conducted in a realistic mobile network simulator. Our results show significant improvements in all aspects for the introduced framework over both the TFRC-based and no adaptation cases.
