Abstract

Un système et un procédé permettant de trouver un chemin entre un nud source et un nud destination dans un réseau sans fil sont décrits. Le procédé consiste à faire établir par le nud source un drapeau de réponse intermédiaire dun message de demande de chemin, à inonder le réseau sans fil à laide du message de demande de chemin, et à faire en sorte quun premier nud intermédiaire comportant un chemin valide vers le nud destinataire réponde au message de demande de chemin par un message de réponse de chemin. Un système et un procédé permettant de trouver le meilleur chemin, et dans lesquels le message de réponse de chemin devient le premier message de réponse de chemin sont également décrits. Le système et le procédé permettant de trouver le meilleur chemin comprennent la sélection, par le nud destination, du meilleur chemin entre ledit nud et le nud source selon les mesures cumulées, contenues dans les messages de demande de chemin reçus par le nud destination, la production dun autre message de réponse de chemin et lenvoi du message au nud source par unidiffusion.
