In this paper, we propose a routing protocol for providing an efficient multicasting service to mobile hosts in IPv6 based networks. The main purpose of our algorithm is to reduce both the number of multicast tree reconstruction and the multicast service disruption time. The proposed protocol satisfies the maximum tolerable transfer delay and supports the maximum tunneling service. The simulation results show that the proposed protocol has better performance in the required multicast tree reconstruction and the multicast service disruption time than the previous protocols.
