In this paper, we propose a cooperative HTTP adaptive streaming system over SDNenabled multiple Wi-Fi networks. The proposed system employs multipath technology to overcome the limited wireless bandwidth. Moreover, SDN technology is used to rapidly respond to unstable wireless network conditions and provide high-quality streaming services. To archive the goal, the SDN controller periodically monitors the traffic information collected from the APs, and based on this information, adjusts video bitrate and data transmission ratio over multiple network interfaces. The proposed system is implemented in real Wi-Fi network environments. Also, it is verified that the proposed system can provide high-quality streaming services.
