Route Choice Research Based on Fast and Hierarchical Mobile Multicast

摘要

Because of the high scalability and efficiency of multicast, more and more people pay attention to mobile multicast. The fast and hierarchical mobile multicast is one of the excellent multicast algorithms, but the transmission path in the fast and hierarchical mobile multicast is not the best. This paper through adds the mobile device's staying time to solve this problem. When a mobile device need to move to a new access router, the mobile device prediction the staying time in new router at first, then the new router according to the staying time to choose a suitable path joins the multicast group. Empirical results show that this new algorithm can optimize routing path and save network resources.
