Title
(EN) METHOD AND EQUIPMENT FOR DATA TRANSMISSION BY AD-HOC NETWORK
(FR) PROCEDE ET EQUIPEMENT POUR LA TRANSMISSION DE DONNEES PAR UN RESEAU AD-HOC
Abstract
(EN)
The invention relates to a method of data transmission by an ad-hoc network of mobile communication equipment (16a, 16b, 16c, 16d), from at least one source equipment (12) to at least one collection terminal (14), by means of mobile relay equipment (16c), in which for each communication equipment, at least one quality factor is updated (QO, Ql, Q2, Q3, Q4, Q5). According to the invention, the quality factor of each relay equipment depends on a history of data transmission, and data transmission from mobile equipment to mobile relay equipment is conditional on the quality factor of the relay equipment capable of receiving the data.
(FR)
La présente invention a trait à un procédé de transmission de données par un réseau ad-hoc d'équipement de communication mobile (16a, 16b, 16c, 16d), à partir d'au moins un équipement source (12) vers au moins un terminal de collecte (14), au moyen d'un équipement de relais mobile (16c), dans lequel, pour chaque équipement de communication, au moins un facteur de qualité est mis à jour (Q0, Q1, Q2, Q3, Q4, Q5). Selon l'invention, le facteur de qualité de chaque équipement de relais dépend de l'historique de la transmission des données et la transmission de données allant de l'équipement mobile à l'équipement de relais mobile est conditionnée par le facteur de qualité de l'équipement de relais capable de recevoir les données.
