Quality Adaptation of SVC-Based P2P Streaming
Peer-to-Peer (P2P) video streaming has become increasingly popular as it is a good enhancement to the traditional Clietn/Server methods in reducing cost and increasing robustness. However, streaming over P2P still suffers from lack of adaptation to the system dynamics. Scalable Video Coding (SVC) shows scalability in partial transmission and decoding. It can support heterogeneous devices in terms of communication bandwidth, display resolution, processing power, and other constraints. In this paper, we propose a P2P streaming architecture leveraging SVC and data scheduling to provide maximum quality adaptation. The proposed quality adaptation mechanisms allow for precise adaptation to device inherent resources limitations and the actual P2P network condition. Moreover, the architecture uses an underlay aware peer selection to improve the P2P overlay topology. The simulation results demonstrate the effectiveness of the quality adaptation of the proposed architecture.
