Abstract

In this paper we present a protocol for providing reliable multicast message delivery in mobile networks. Our protocol efficiently tracks message delivery and allows for reliable message delivery in an environment where the mobile multicast group experiences frequent adds and drops. Furthermore, our protocol allows group changes and message tracking to be handled locally, which translates to shorter breaks in service as mobile users move from cell to cell. RelM is implemented on top of reliable multicast IP protocols developed for high-speed networks and thus allows multicast groups to contain both fixed and mobile users.
