AVS: An Adaptive P2P Video Streaming Scheme with Frame Type Aware Scheduling

In this paper, we present a video streaming scheme in peer-to-peer network, in which frame type aware scheduler adaptively adjusts the stream rate based on the estimated network bandwidth from the supplying peer nodes. The proposed frame type aware scheduler allocates the request quantity to each partner based on its variable network bandwidth, and decreases uselessly received video frames which not only consumes the available bandwidth but also no contribution for stream quality. We evaluated the adaptation scheme through extensive network simulations, and the result demonstrates that AVS significantly decreases uselessly received video frames without degrading streaming quality. Especially, when the bandwidth supply is insufficient, the effectiveness of proposed scheme significantly increases.
