Abstract
A system includes a server, a plurality of end devices, and at least one gathering gateway serving as a relay between the server and the end devices. The server creates at least one group and allocates end devices to each group created; defines, for each group, instances of a group reception window separated by a period so as to occur at deterministic instants; receives uplink frames coming from end devices; for such end device allocated to a group, acknowledges the uplink frames received in a downlink frame transmitted in multicast mode, in such group reception window defined for said group, said downlink frame including a group acknowledgement for all the uplink frames sent by end devices of the group during the period preceding said instance of the group reception window; and, for such end device that is not allocated to a group, acknowledges the uplink frames received in unicast mode.
