摘　　要：随着科学技术的飞速发展,多媒体通信的需求导致了组播技术的快速进步。如何节约网络资源,为移动设备提供更好的支持也引起了人们的普遍关注。由于组播具有可扩展性强、高效的特点,因此移动组播的应用已经得到了越来越多的关注。本文根据快速分层移动组播现有算法中的传输路径问题,介绍一种新的路由路径选择方法。该算法依据移动节点在新接入点停留的时间长短,选择不同的数据传输路径加入组播。可以优化组播分组的传输路径,有效减少网络资源的浪费。With the rapid progress of science and technology, the requirement of multimedia communication let to the rapid advancement of the multicast technology. How to save network resources and determine the best way to provide services to mobile devices is the most important issue need to solve. As multicast naturally has the merit of high scalability and efficiency, more and more people pay attention to mobile multicast. Based on the transmission path problem of the fast and hierarchical mobile multicast, this paper introduces a new method. which is an improved algorithm based on the staying time of mobile devices under new access router, through prediction staying time mobile devices, it chooses a better path to join multicast. This new method can optimization routing path and save network resources.
