The method includes starting a scan mode at a first node (200) having data to send; and determining whether data to send has been transmitted to the first node from an upstream node or a downstream node. If the data to send was received from a downstream node, the first node begins a scan mode. If the data to send was received from an upstream node, the first node begins an ADV event.
