Abstract
(EN)
A routing method in the wireless network and a communication device using the same is provided. The routing method in the tree-based wireless network includes acquiring an optimal route using a table which is recorded based on received information on neighbor nodes and received information on lower nodes of the neighbor nodes, and transmitting a packet through the optimal route. Accordingly, tree-based mesh routing which performs route discovery block by block is used in order to increase the efficiency of route discovery, and a packet is transmitted through an optimal route so that communication costs can be reduced.
(FR)
L'invention concerne un procédé de routage dans un réseau sans fil et un appareil de communication permettant de mettre en oeuvre ledit procédé. Le procédé de routage dans un réseau arborescent sans fil consiste à acquérir un chemin optimal à l'aide d'une table enregistrée en fonction d'informations provenant de noeuds voisins et de noeuds inférieurs desdits noeuds voisins, et à transmettre un paquet via le chemin optimal. En conséquence, on utilise un routage par maillage arborescent qui permet d'effectuer une recherche de chemin bloc par bloc afin d'augmenter l'efficacité de ladite recherche, un paquet étant transmis via le chemin optimal de sorte que les coûts de communication peuvent être réduits.
