A method for distributing a packet to a plurality of moving nodes comprising receiving a packet containing at least a message, a sender identifier, a location of a sender, an identifier for a relay node and distance from the sender and the relay node, determining if a node receiving the packet is the relay node and immediately distributing the packet to a plurality of moving nodes if the receiving node is the relay node. If the receiving node is not the relay node, the method further comprises steps of waiting a set period of time, determining if a packet is received from a different sender containing the same message, within the period of time and distributing the packet to a plurality of moving nodes if a packet containing the same message is not received within the period of time. The distributed packet includes an identifier for a successive relay node.

L'invention concerne un procédé de distribution d'un paquet à une pluralité de nuds mobiles comprenant la réception d'un paquet contenant au moins un message, un identifiant d'envoyeur, un emplacement d'un envoyeur, un identifiant pour un nud de relais et la distance de l'envoyeur et du nud de relais, la détermination si un nud recevant le paquet est le nud de relais et la distribution immédiate du paquet à une pluralité de nuds mobiles si le nud de réception est le nud de relais. Si le nud de réception n'est pas le nud de relais, le procédé comprend en outre les étapes d'attente pendant un intervalle de temps défini, de détermination si un paquet contenant le même message est reçu d'un envoyeur différent dans l'intervalle de temps, et de distribution du paquet à une pluralité de nuds mobiles si un paquet contenant le même message n'est pas reçu dans l'intervalle de temps. Le paquet distribué comprend un identifiant pour un nud de relais successif.
