Abstract

L'invention concerne un système à topologie distribuée, décentralisée, destiné à un réseau local d'entreprise ou analogue. Des dispositifs contenus dans le système contrôlent la qualité de canal. Si la qualité de canal se révèle insuffisante, une réévaluation du canal est effectuée dans le but d'identifier un meilleur canal. Ce nouveau canal est ensuite communiqué à d'autres dispositifs du réseau, de sorte que tous les dispositifs peuvent communiquer sur ce nouveau canal.
