Abstract
A method and system to acknowledge a multicast message includes informing each node in a network about each multicast group to which it belongs, a relative position in each multicast group to which it belongs, and a group size of each multicast group to which it belongs, transmitting the multicast message, and transmitting, by each node in the multicast group, an acknowledgment in an assigned slot, which is determined by the relative position.
