A Logical Ring Reliable Multicast Protocol for Mobile Nodes

A protocol for the reliable multicast of data to mobile hosts is described. A logical ring is maintained between all the base stations that handle the multicast traffic of the same multicast group. A token passing protocol enforces a consistent view between all base stations with respect to the frames that are considered delivered to all mobiles. The interaction of the reliable multicasting and the handoff events of the mobiles is controlled by a special handoff protocol. A description of the management protocol is also given. We use simulation results to illustrate the feasibility of the approach and reveal the performance interplay between the base station buffer size and the token rotation frequency.
