Design and Evaluation of a Protocol for Atomic Multicast among Mobile Hosts

In this work we extended Acharya and Badrinath’s [2] reliable multicast protocol for mobile computing so as to provide also for atomicity of message delivery. In this protocol, named AMC, a multicast message is only delivered to all mobile host destinations if these are reachable during a first phase of the protocol. After a multicast is either committed or aborted, the protocol guarantees that all the mobile hosts are eventually informed about the final status of the multicast. In this paper we discuss the protocol and present results of our simulations.
