Low-delay mesh with peer churns for peer-to-peer streaming

In this study, we discuss how to provide low-delay peer-to-peer streaming with high video quality by considering mesh design with backup parents. To achieve robustness against peer churns, each peer has a certain number of streaming parents and backup parents. We have designed a distributed algorithm that constructed a low-delay mesh and at the same time achieved a certain stream continuity for the peers. We have conducted extensive simulations to study the performance of our algorithms. The results show that our distributed algorithm achieves a lower source-to-peer delay as compared with a traditional scheme. Our results have shown that peer-to-peer live streaming can be delivered in short delays while providing a high level of quality, despite peer churns and the lack of a centralized planner.
