DASU: High Quality Video Streaming Over Multiple Wireless Access Network Using Real Time Adaptive Algorithm

Prathibha T P

Abstract: Video streaming is gaining popularity among mobile users. Presently everybody has a hand held devices such as smart phones and tablets, all are equipped with multiple wireless network interfaces like Wi-Fi, 3G, Bluetooth etc. This Paper Dynamic Adaptive Streaming over UDP (DASU) mainly focuses on how efficiently and cost-effectively utilizes multiple links to improve video streaming quality. In order to maintain high video streaming quality while reducing the wireless service cost, in this paper the optimal video streaming process with multiple links is formulated as a Markov Decision Process (MDP). . The reward function is designed to consider the quality of service (QoS) requirements for video traffic. To solve the MDP in real time, this paper proposes a Real Time Adaptive Algorithm to obtain a solution. The proposed algorithm works well with the system by doing some evaluation to achieve the QoS such as the startup latency, playback uency, and average playback quality. Experiment results demonstrate the feasibility and effectiveness of the proposed adaptation algorithm for mobile video streaming applications.
