Abstract: In a wireless communication system configured to have a plurality of nodes, any one of the nodes receives a broadcast message from the nodes adjacent thereto, and calculates a reception time point variation that is difference between a time point when the message is received for each of the adjacent nodes and a time point when the preceding message is received. The reference time of the node is corrected based on the variation calculated for each of the adjacent nodes.
