CA 2484495

A mobile ad hoc network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the plurality of nodes together. The method of tracking traffic includes each node monitoring traffic communicated between nodes in the network, each node generating traffic information (112,114) based upon how much traffic is being communicated between various nodes in the network, and each node storing the traffic information in a traffic database. The traffic information may be based upon bandwidth and may include at least one of error rate, end-to-end delay, end-to- end delay variation, hop count, expected path durability, and priority. Each node may discover and select traffic routes based upon the stored traffic information.

Selon la présente invention, un réseau ad hoc mobile comporte une pluralité de noeuds mobiles radio et une pluralité de liaisons de communication radio se connectant à la pluralité de noeuds. Ce procédé de suivi du trafic consiste au niveau de chaque noeud à surveiller le trafic communiqué entre des noeuds du réseau, à engendrer des informations de trafic (112, 114) en fonction de la quantité de trafic communiqué entre divers noeuds du réseau et à stocker les informations de trafic dans une base de données de trafic. Lesdites informations dudit trafic peuvent se baser sur la largeur de bande et peuvent comporter au moins un taux d'erreurs, un retard de bout en bout, une variation de retard de bout en bout, un dénombrement de sauts, une durabilité de voie attendue, et une priorité. Chaque noeud permet de découvrir et de sélectionner des routes de trafic en fonction des informations stockées sur le trafic.
