Title (EN) INCIDENT BROADCAST RETRANSMISSION IN A VEHICULAR NETWORK
(FR) RETRANSMISSION DE DIFFUSION D'INCIDENT DANS UN RÉSEAU DE VÉHICULES
Abstract:
(EN) A system for transmission of incident information includes maintaining a table of RSSI values for a plurality of stations. When an incident is detected, the system first sends a broadcast packet with incident information, and next sends a unicast packet to any station below a particular RSSI threshold until the unicast packet is acknowledged or a retransmission interval passes.
(FR) Un système de transmission d'informations sur un incident suppose la gestion d'une table de valeurs RSSI pour une pluralité de stations. Lorsqu'un incident est détecté, le système commence par envoyer un paquet de diffusion contenant des informations sur l'incident. Il envoie ensuite un paquet en unidiffusion à une quelconque station au-dessous d'un seuil RSSI particulier jusqu'à ce que le paquet en unidiffusion fasse l'objet d'un accusé de réception ou jusqu'à ce qu'un intervalle de retransmission s'écoule.
