A dynamic service range-based multicast routing scheme using RSVP in mobile IP networks

We propose a multicast routing scheme for an efficient and reliable support of multicast service to mobile hosts in IPv6 based networks. The purpose of this paper is to develop an algorithm to reduce both the number of multicast tree reconstruction and the multicast service disruption time. The proposed multicast routing scheme is a hybrid method using the advantages of the bi-directional tunneling and the remote subscription proposed by the IETF Mobile IP working group. The proposed scheme satisfies the maximum tolerable transfer delay time and supports the maximum tunneling service. The simulation results show that the proposed scheme has a better performance in the number of multicast tree reconstruction and the time of multicast service disruption than the previous schemes does
