Description

The invention relates to a method for disseminating a message in an incomplete radiocommuniation network (2) comprising a variable number of subscribers (4- 12) whereby each subscriber has a device that sends and receives messages in addition to a positioning system that determines a global position. Once the message is received, subscribers (9-12) determine their own position and the distance from the transmitter of said message, whereby the transmitter of the message is also a subscriber (6-12). They send the message together with their current position to other subscribers (6-12) when a specific amount of waiting time (t) has elapsed, whereby the waiting time (t) decreases monotonously as the distance (2) increases. This enables the message to be transmitted quickly without putting any strain on the radiocommunication network.

L'invention concerne un procédé permettant de diffuser une information dans un réseau de radiocommunication (2) incomplet comportant un nombre variable d'abonnés (4-12) assurant la retransmission de l'information. Chaque abonné possède un dispositif d'émission et de réception des informations et un système de positionnement permettant de déterminer sa position mondiale. A réception de l'information, les abonnés (6-12) déterminent leur propre position et la distance d qui les sépare de l'émetteur de l'information qui est également un abonné (6-12). Ensuite, ils envoient l'information avec leur propre position à d'autres abonnés (6-12) au bout d'un temps t déterminé qui décroît à mesure que la distance d augmente. Ce procédé garantit une transmission rapide de l'information sans charger le réseau de radiocommunication (2).
