            designating a first anchor of a plurality of anchors as an initiator for a first ranging round for determining a position of a node in a communication network comprising the node and the plurality of anchors, wherein designating the first anchor as the initiator causes the first anchor to initiate the first ranging round by sending a first ranging initiation message; and
