dc.description.abstract | This work presents a mobile data offloading system for video streaming services over software-defined networking (SDN)-enabled wireless networks. The goal of the proposed system is to alleviate cellular network congestion by offloading parts of video traffic to a WiFi network while improving video quality of all users by efficiently and fairly sharing the limited long term evolution (LTE) resources. In the proposed system, SDN architecture is applied to the wireless network environment to quickly react to time-varying network conditions and finely control the amount of traffic transmitted through LTE and WiFi networks. Under the SDN-enabled wireless environment, we frame the mobile data offloading problem for video streaming services as an asymmetric Nash bargaining game to address conflict among competitive mobile users. Furthermore, we propose a resource allocation algorithm that pursues an effective trade-off between global system utility and quality-of-service fairness among users. The system is fully implemented using ONOS SDN controller and Raspberry PI-3-based mobile devices, and performance is evaluated over real wireless networks. | - |
