A station stores (E602) data relating to the message in a table on receipt of a message, including message identifiers (ID, ISS) and the identifier (TSS) of the station sending the message. ID and ISS are compared with previously stored identifiers. A group of stations which are both final and intermediate destination stations are sought in the table of sending station and a second message is broadcast if the message identifier differs from the stored identifiers and the group includes at least one station different from the one which sent the message. |
