As the number of user of group services increases, ISP, service provider, and service user need efficient delivery of service. Although multicast delivery can provide the efficient delivery of service, it is not used widely because of deployment and management problems. As an alternate solution, many overlay multicast mechanisms are proposed, especially in overlay multicast for supporting mobility is proposed. In this paper, the authors introduce a real-time data delivery mechanism for overlay multicast with focus on supporting mobile node.
