摘要：P2P live streaming networks recently become an emerging research topic. In such multimedia steaming networks, autonomous users cooperate with each other to provide a self-organizing, distributed, scalable, and cost-efficient transmission environment. Due to the mismatch problem between the overlay network and the physical network, dynamics of peers, and peers’ self-interested, low start-up delays, full cooperation, and stable playback quality can not be guaranteed. Therefore, how to incentivize the participanting peers to have the willings to provide more resources and how a group of geographically neighboring peers cooperate with each other to achieve better streaming performance are all important issues. In this paper, we propose the design of a two layered hybrid tree-push/mesh-pull overlay network with considering the problems of locality-aware of peers and incentive schemes. We propose the schemes and algorithms to overcome the mismatch problem between the overlay network and the physical network, reduce the transmission latency, and provide a fully cooperative, and reliable P2P streaming environement.
