Supporting QoE-Aware Live Streaming Over Peer-to-Peer Network

QoE-aware (Quality of Experience) dynamic adaptive streaming over HTTP in Peer-to-Peer (P2P) networks has attracted researchers during the last decade due to the increasing multimedia applications over Internet. In this paper, we propose a super-peer architecture which can reduce the delay of live streaming as well as increase the delivery ratio. Furthermore, we also propose a rate migration control algorithm over our proposed system model which enhances QoE of clients by switching different video quality versions depending upon their current network status. This model can able to provide different quality versions of the same video as representation, where each representation streams to all super-peers over our proposed multi-overlay system model. The performance of proposed live streaming mechanism in super-peer network is studied through simulation and it is observed that it outperforms state-of-the-art live streaming in peer-to-peer networks.
