Abstract
(EN)
The method of the invention is implemented in ad hoc communications network employing at least two-hop routing and wherein each node in the network employs an omnidirectional send/ receive capability. Each node keeps a near neighbour database (NND) updated by receiving of messages. Each Othernode in the network, the message of which was received by Mynode in a time period T, is a candidate for becoming a relay for transmitting Mynode's messages. The probability of an Othernode to become a relay for Mynode is higher for a larger amount of candidates Othernode has in its NND. The probability for the Othernode to become a relay is higher the larger its distance from Mynode.

Le procédé de la présente invention est mis en œuvre dans un réseau de communications ad hoc qui emploie un routeur à au moins deux bonds et dans lequel chaque nœud du réseau utilise une fonctionnalité « transmission/réception » omnidirectionnelle. Chaque nœud conserve une base de données de voisin proche (NND) mise à jour par la réception de messages. Chaque Othernode (Autre nœud) dans le réseau dont le message a été reçu par Mynode (Mon nœud) sur une période T, est un candidat pour devenir un relais de transmission des messages de Mynode. La probabilité qu'un Othernode devienne un relais pour Mynode est supérieure pour une plus grande quantité de candidats que Othernode a dans sa base de données NND. Plus la distance entre Othernode et Mynode est grande, plus il est probable qu'Othernode devienne un relais.
