setting a plurality of anchors to a primary setting;
broadcasting, by the plurality of anchors, synchronization messages;
sending, by the plurality of anchors, responses to the synchronization messages;
performing, by the plurality of anchors, a room consensus to determine probabilities of obstacles between the plurality of anchors;
sending, by the plurality of anchors, proposals of one or more clusters based on the room consensus; and
forming, by the plurality of anchors, one or more clusters based on the proposals, wherein:
setting the plurality of anchors to the primary setting comprises setting each anchor to an initial cluster; and
the synchronization messages comprise a cluster index set to an initial value that indicates the initial clusters are temporary.
