With advent of various mobile devices with powerful networking and computing capabilities, the users' demand to enjoy live video streaming services such as IPTV with mobile devices has been increasing rapidly. However, it is challenging to get over the degradation of service quality due to data loss caused by the handover. Although many handover schemes were proposed at protocol layers below the application layer, they inherently suffer from data loss while the network is being disconnected during the handover. We therefore propose an efficient application-layer handover scheme to support seamless mobility for P2P live streaming. By simulation experiments, we show that the P2P live streaming system with our proposed handover scheme can improve the playback continuity significantly compared to that without our scheme.
随着各种具备强大网络和计算能力的移动设备的出现，用户使用移动设备享受诸如IPTV等直播视频流服务的需求迅速增长。然而，由于切换导致的数据丢失，克服服务质量的下降具有挑战性。尽管在应用层以下的协议层提出了许多切换方案，但在切换期间网络断开连接时，它们本质上会遭受数据丢失。因此，我们提出了一种高效的应用层切换方案，以支持P2P直播流的无缝移动性。通过模拟实验，我们表明，与没有我们方案的情况相比，采用我们提出的切换方案的P2P直播流系统可以显著提高播放连续性。
