A new mobile multicast method based on the THMLD protocol

Some mobile multicast schemes have been proposed in the past few years, but most of them study the reconstruction of multicast delivery tree, but little consider the mobile group membership management. In this paper, we propose a new mobile multicast method based on Two-Hop Multicast Listener Discovery (THMLD) protocol which provides the mobile multicast membership management function by forwarding the MLD messages to its neighboring subnets. To evaluate its performance, we set up the simulation platform and compare it with the traditional mobile multicast methods. The simulation results show that the proposed method can reduce the multicast join delay significantly.
