Abstract
An improved system and method of transmitting messages to multiple destination nodes is provided, in which a message from a source node is addressed to a multicast-broadcast address, and multiple destination node addresses are included in the message header. Destination nodes which successfully receive the transmission calculate a timeslot in which to transmit an acknowledgement message based on the position of their address in the message header. The source node can then provide a retransmission to destination nodes which did not successfully receive the transmission as either a multicast-broadcast or a unicast communication depending on acknowledgement messages received.
