This thesis addresses the challenge of managing industrial mobile applications in IoT systems based on the 6TiSCH architecture defined by the Internet Engineering Task Force (IETF). Industrial applications demand high reliability and low latency communication. In addition, node mobility introduces additional issues, such as synchronization loss, inefficient resource allocation, communication delays, which may compromise the correctness of the application. To meet the stringent requirements of these applications, a novel scheduling algorithm for 6TISCH network has been developed, based on two key mechanisms. Multiple re-transmissions is used to enhance reliability and multi-channel scheduling to improve scalability and reduce the overall delay. The effectiveness of the proposed solution has been validated through extensive simulations using the OMNeT++ . The results obtained show significant improvements in network performance, with respect to previous algorithms, with marked reductions in communication delays and a substantial increase in Packet Delivery Ratio (PDR). The results demonstrate the algorithm's potential to address the specific demands of industrial IoT applications in dynamic environments, while highlighting the inherent trade-offs between reliability, latency, and network capacity. This work lays the foundation for future advancements in dynamic scheduling for industrial IoT systems.
