An Efficient Source Mobility-based Multicast Scheme for Mobile Hosts in Mobile-IPv6 Networks

摘要

In mobile Internet, the host grouping maintenance or the multicast delivery tree for multicasting algorithm becomes a major issues. In this paper, we explore the issues of mobile Multicast scheme using Mobile-IPv6. Specifically, we address operation scenarios when a mobile host is a source as well as a recipient of a given multicast operation using MLD(Multicast Listener Discovery) scheme, and the proposed MLD-based multicasting protocol, MIP-MLD uses a smooth handoff technique to reduce the service disruption for the multicast session during the handoff. We compared our scheme to existing approaches by cost analysis model, and gained an improved performance in terms of the multicast delivery path.
