An efficient multicast delivery scheme to support Mobile IP

Once mobile nodes move into another network, Mobile IP is employed for the remaining unicast services. However, multicast services become unavailable because of topology changes. A multicast scheme is proposed based on our Domain-based Mobile IP (K.D. Wu et al., 1998). Multicast services are divided into two types: Intra-domain service and Inter-domain service. The article identifies mobile nodes joining the Internet where they can acquire benefits of multicasting and its potential values, as for stationary nodes it does not matter they are at Home Network or Foreign Network. Finally the comparison of multicast delivery schemes for the mobile environment is presented.
