Title
(EN) COST BASED ROUTING PROTOCOL
(FR) PROTOCOLE D'ACHEMINEMENT FONDE SUR LE COUT
Abstract
(EN) A wireless network in which each message transmitted by a node is received by all the neighboring nodes. Each node maintains a table containing entries specifying the cost of transmission from that node to each of the other nodes in the network. Each message frame includes a field containing the remaining cost of transmission of the frame to the destination node for the message. When a node receives a message frame for which it is not the destination it compares the remaining cost with the cost contained in the table entry for the destination node. If the table entry cost is less than the remaining cost, the node decrements the remaining cost and retransmits the frame. Otherwise it discards the frame.
(FR) L'invention concerne un réseau sans fil dans lequel chaque message transmis par un noeud est reçu par tous les noeuds avoisinants. Chaque noeud tient une table contenant des entrées spécifiant le coût de la transmission entre ce noeud et chaque autre noeud du réseau. Chaque trame de message comprend un champ contenant le coût de transmission restant pour acheminer la trame vers le noeud destinataire. Lorsqu'un noeud reçoit une trame de message dont il n'est pas destinataire, il compare de coût restant avec le coût inscrit dans la table pour le noeud destinataire. Si le coût entré dans la table est inférieur au coût restant, le noeud décrémente le coût restant et retransmet la trame. Si tel n'est pas le cas, il élimine la trame.
