A low-time-delay scheduling algorithm for Video on Demand service over P2P networks

We are interested in providing Video-on-Demand (VoD) streaming service to a large population of clients using peer-to-peer (P2P) approach. One of the drawbacks of the current P2P architectures is that which have long start-up delays. In this paper, a novel scheme is envisioned to effectively provide a Video-on-Demand (VoD) over P2P networks. The scheme covers three main methods, namely first copying, grouping based on parts and priority scheduling. In fact, all above phases work synchronously to achieve a good performance. Extensive simulation results demonstrate that this new scheduling algorithm not only achieves low start-up time and high streaming continuity but also keeps a good network throughput even in hard network conditions.
