Adaptive rate control scheme to improve QoS of multimedia streaming application

This paper presents an adaptive rate control scheme for streaming-based content sharing service which delivers multimedia contents from a user device to another device or seamlessly redirect streaming service across heterogeneous user devices. In proposed scheme, a streaming server adjusts video quality level according to the network and client status. Our scheme is different from other rate control schemes because the video quality at the server is decided not only based on the available bandwidth, but also on the device characteristics and bandwidth requirement at the access network. Through the simulation, we prove that our scheme improves the network stability and quality of streaming service by appropriately adjusting the quality of video stream.
