A Data Reception Method to Reduce Interruption Time in P2P Streaming Environments

In recent years, there has been an increasing interest in P2P (Peer-to-Peer) streaming environments. In P2P streaming environments, compared with the traditional server-client model, the load of the server can be reduced by transmitting the divided streaming data (pieces) among clients. However, when bandwidths between clients are narrow, interruption occurs since clients cannot receive the necessary piece of data until the time to play it. In this paper, we propose a data reception method to reduce interruption time in P2P streaming environments. Our proposed method calculates the importance of each piece which takes into account the immediacy and the scarcity of the piece. The evaluation results show that our proposed method can reduce the interruption time for peers in a P2P environment compared with conventional methods.
