CA 2753245

A method for transmitting data in vehicular network comprising determining a communication window between at least two nodes, grouping a plurality of fragments of content together into an aggregate fragment block, forwarding the aggregate fragment block to a target node and assembling the plurality of fragments into the content. The content is divided into the plurality of fragments. A fragment signature is generated for the fragments that contain fragment index information regarding each fragment. Each fragment is unambiguously identified by its signature. A number of fragments grouped into the aggregate fragment block is dependent on the communication window.

L'invention porte sur un procédé de transmission de données dans un réseau véhiculaire, comprenant la détermination d'une fenêtre de communication entre au moins deux nuds, le regroupement d'une pluralité de fragments de contenu ensemble en un bloc de fragments agrégés, le transfert du bloc de fragments agrégés à un nud cible et l'assemblage de la pluralité de fragments dans le contenu. Le contenu est divisé en la pluralité de fragments. Une signature de fragment est générée pour les fragments qui contiennent des informations d'indice de fragment concernant chaque fragment. Chaque fragment est identifié de façon non ambiguë par sa signature. Un nombre de fragments groupés dans le bloc de fragments agrégés dépend de la fenêtre de communication.
