| 摘 要： | Mobile multicast is important for the emerging applications such as mobile video or audio conference and mobile IPTV. Some mobile multicast schemes have been proposed in the past few years, but most of them study the reconstruction ofmulticast delivery tree, and few consider the group membership management for mobile subscribers. In this paper, we propose a new mobile multicast method based on the Two-Hop Multicast Listener Discovery （THMLD） protocol which provides the mobile multicast membership management function by forwarding the traditional MLD messages to its neighboring subnets. To evaluate its performance, we analyze the THMLD and set up the simulation platform to compare it with the several traditional mobile multicast methods. The results show that THMLD can reduce the multicast join time, and the THMLD-based mobile multicast method can reduce the multicast join delay at a cost of increasing additional multicast maintenance cost.
