Abstract
A method can include receiving at a cluster head, a multicast/broadcast packet from a base station. The method can also include monitoring, at the cluster head, to detect whether any members of a cluster of the cluster head responds to the multicast/broadcast packet with a negative acknowledgment directed to the cluster head. The method can further include, when a result of the monitoring is no detection of any negative acknowledgments, and the cluster head successfully received the multicast/broadcast packet, sending, by the cluster head, a general acknowledgment of the multicast/broadcast packet to the base station.
