MP-FMIPv6: MLD Proxy Based Fast Multicast Protocol for Mobile IPv6

摘要

Mobile multicast is a research hotspot and can provide many applications. Some schemes have been proposed to support the mobile subscriber, but most of them study the construction algorithm of dynamic multicast delivery structure and use the analysis and simulation to evaluate the performance, little concern on the multicast disruption time and protocol cost. In this paper, we propose a Multicast Listener Discovery (MLD) Proxy based Fast Multicast protocol for Mobile IPv6 (MP-FMIPv6), and implement simplified MLD proxy function on Home Agent (HA) and extend MLD host part function on MN. The analytical results show that MLD proxy based fast multicast can reduce multicast disruption time and cost. To evaluate the performance of proposed scheme in real applications, we setup a test-bed and compare it with Bi-directional Tunneling (BT) and Remote Subscription (RS) methods. The experiment results show that the proposed scheme nearly improves the multicast disruption time by 2.4 times and 3.66 times, and saves the cost about 19.1% and 57.4%, respectively.
