| 摘 要： | 根据无线Ad Hoc网络环境下P2P流媒体数据传输的特点,提出一种工作在P2P数据拓扑层面的,不依赖于底层物理网络的节点配置和特定的路由算法的优化传输方案.在发送数据时,节点结合应用层视频分片的重要性和网络状况动态地调整传输层参数,从而减小重要数据的传输延时和播放超时的概率.仿真结果验证了本方案对于改善服务质量和减小控制信令开销的有效性.

| Abstract: | Based on the features of P2P streaming model over wireless Ad Hoc networks,we propose a transmission optimization mechanism which works at the P2P data topology level and is independent of the underlying networks.According to importance of video slices and network conditions,peers adjust transport layer parameters adaptively to reduce transmission delay for important slices.Experiment results show the effectiveness on improvement of quality of service and reduction of control overhead. |
