Abstract
Point­to­Multipoint ARQ protocols are required to guarantee the correct delivery and proper
sequencing of messages being sent from one source to multiple destinations. A source of ineffi­
ciency for such protocols is that the transmitter requires acknowledgements from all receivers
before it considers that a message has been correctly received. To address this inefficiency, we
propose a scheme in which the set of destinations is split into disjoint groups. The transmitter
