Abstract
An operation method of a first communication node operating as a current reference grand master (GM) node in a vehicle network may comprise: transmitting a first synchronization message including a first reference time of the first communication node; receiving a first response message from a second communication node, the first response message including a first synchronization offset indicating a difference between a first local time of the second communication node and the first reference time; receiving a second response message from the second communication node, the second response message including a second synchronization offset indicating a difference between the first local time and a second reference time of a third communication node operating as a GM node; and determining the first communication node or the third communication node as a first reference GM node based on a result of comparison between the first synchronization offset and the second synchronization offset.
