Abstract: This thesis explores the role of Industrial Wireless Sensor Networks (IWSNs) within the framework of Industry 4.0, emphasizing their significance in enhancing efficiency and responsiveness in industrial operations. IWSNs are crucial for interconnecting sensors and actuators, enforcing Service Level Agreements (SLAs) for high Quality of Service (QoS) in terms of reliability and latency. Mainly, IWSNs rely on deterministic protocols at the Medium Access Control (MAC) layer to minimize uncertainties. However, centralized scheduling approaches, crucial for optimal performance, face practical challenges. This study proposes a Software Defined Network (SDN) solution for IWSNs, ensuring reliable control plane communication and introducing a call admission system for effective centralized resource allocation based on devices' QoS requirements. The thesis also presents an accurate and energy-efficient topology discovery and link quality estimation method, critical for preventing resource overestimation or underestimation. Additionally, an efficient solution for maintaining scheduled SDN networks over time-varying wireless links is introduced, minimizing control traffic and reconfiguration time while preserving SLAs for critical flows. This research provides valuable insights into advancing IWSNs in the context of Industry 4.0, addressing key challenges for enhanced performance and adaptability. ; Cette thèse explore le rôle des réseaux de capteurs sans fil industriels (IWSNs) dans le cadre de l'Industrie 4.0, mettant en avant leur importance dans l'amélioration de l'efficacité et de la réactivité des opérations industrielles. Les IWSNs sont cruciaux pour l'interconnexion des capteurs et actionneurs, appliquant des accords de niveau de service (SLAs) pour une qualité de service (QoS) élevée en termes de fiabilité et de latence. Principalement, les IWSNs s'appuient sur des protocoles déterministes au niveau du contrôle d'accès au support (MAC) pour minimiser les incertitudes. Cependant, les approches de planification ...
