L’objectif de cette thèse est la mise au point de nouveaux mécanismes pour améliorer la qualité de service des réseaux LPWAN dans le contexte des Villes Intelligentes. Dans un premier temps, nous analysons l'évolution de la qualité de service en observant le taux de paquets erronés (PER) de la couche MAC de différents standards LPWAN, soumise à la densification des réseaux. Dans un deuxième temps, nous nous concentrons sur la technologie LoRa et nous identifions les verrous à lever, notamment le taux de paquets rejetés, les collisions entre paquets et le nombre de passerelles déployées, dans différents scénarios de densification des réseaux. Nous introduisons alors un nouveau protocole appelé LoRa+ basé sur « l'écoute avant de parler » (Lis...
