摘要

为了提高Mesh网结构下的流媒体传输效率,在分析了当前Mesh网流媒体传输方法基础上,基于Mesh网的结构特点,通过把P2P技术和H2O流媒体放置复制算法相结合,设计并实现了一种综合考虑Router和Client的Mesh网流媒体传输方法,分别探讨了非P2P和P2P模式下的流媒体发现、路由和传输机制,并通过仿真对算法的性能进行了评估.仿真表明,与同类算法相比,该算法在性能上有明显提高.%To improve the efficiency of flow media transmission in Mesh networks,a new Mesh network flow media transmission method that considers Routers and Clients comprehensively was designed and realized on the basis of analysis of the current Mesh network flow media transmission method and the Mesh network structure characteristics.The mechanisms of discovery,routing and transmission of flow media under non-P2P and P2P modes are discussed.The performance of the algorithm is evaluated with a simulation method.The simulation results show that,compared with similar algorithms,the performance of the algorithm proposed in this paper has more obvious improvement.
