摘要：

This paper presents an energy-efficient Hypertext Transfer Protocol (HTTP) adaptive streaming system to maximize the overall quality of video streaming services for all clients in an energy-efficient way over software-defined networking (SDN)-enabled Wi-Fi access points (APs). To achieve this goal, the proposed system employs multi-path technology to overcome the limitations of a single Wi-Fi AP and adopts the Luby transform (LT) code as forward error correction to support flexible and reliable data transmission via multiple APs. Furthermore, the SDN controller manages the segment bitrate, code rate of the LT code, and video packet transmission via multiple APs based on a global view of the network status, buffer occupancy, and energy consumption. The proposed system is implemented by using network simulator 3 (NS-3) to verify on a large-scale simulation environment and fully implemented in a real testbed to demonstrate its feasibility. The experimental results show that the proposed system can provide superior performance with lower energy consumption than any other existing system.
