ABSTRACT
P2P systems similar to file sharing applications are being used vastly due to unrestricted nature of thesesystems. Their unrestricting comes from their ability to cooperate and aggregate peer’s resources andtheir scalability. On the other side, today technologies are traditional client-server applications. Theseapplications can perform strongly but they are not scalable due to limitations on server resources. Thislimitation of the client/server technology leads designers to use alternative technologies mainly P2P. Asa streaming system, P2P streaming network can be formed into two types, Tree-based and Mesh-based.In this paper a new mesh-based P2P system named Head-Tail streaming is proposed. Head-Tailsimplifies packet scheduling and node failure recovery by using paired-peer sending and node failureprediction. Our system outperforms ordinary systems comparing as delay and receive time. Our systemperforms better than ordinary systems based on two reasons :Overlapping sequence of chunks and nodereplacement policy.
