Towards Centralized Management for Video Streaming Over Enterprise Wireless LANs

To satisfy the need for ubiquitous connectivity of their customers, many enterprises (e.g., hotels, cafes and commercial centers) deploy EWLAN (Enterprise WLAN). In these networks, video streaming is both one of the most popular and challenging applications. To improve the overall users QoE in EWLAN, we propose to address simultaneously the resource bottlenecks that can occur on wireless links as well as the lack of overall bandwidth that can be experienced on the Internet access link. We propose a dynamic video Streaming Management based on software defined enterprIse wireLEss LANs (SMILE), an SDN framework which dynamically allocates the bandwidth among different access points based on their workloads and on the available bandwidth. We evaluate SMILE over several adaptive video streaming performance metrics: instability, rebuffering, and average video quality. The results demonstrate an improvement for these parameters with different adaptation logics when SMILE is in use.
