    Abstract: A method of synchronizing wireless devices includes establishing a recurring sequence of frequency channels at which the wireless devices are to communicate. The frequency channels are divided into a plurality of groups. Synchronization information is transmitted at a respective first frequency channel in each of the groups of frequency channels during a first sampling time period. One of the groups of frequency channels is selected. A wireless device is used to sample each of the frequency channels in the selected group during the first sampling time period. Non-synchronization information is transmitted after the first sampling time period. Synchronization information is transmitted at a next respective frequency channel in each of the groups of frequency channels during a next sampling time period. The next sampling time period occurs after the transmitting of the non-synchronization information.

    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.
