Abstract

Multiple modern applications in Industrial IoT and autonomous systems need deterministic wireless networking, but current Wi-Fi cannot provide these requirements for time-sensitivity. This thesis presents a proof-of-concept implementation that integrates IEEE 802.1Qbv Time-Aware Shaper (TAS) with IEEE 802.11 Enhanced Distributed Channel Access in Wi-Fi 7 Multi-Link Operation (MLO) networks. The hybrid approach combines deterministic TAS scheduling with contention-based EDCA access.The TAS controls the traffic distribution and EDCA handles wireless transmission. Using a MLO based Network allows transmission of data through different links. The main contributions are (1) a load-balancing algorithm for priority and queue-aware link selection of MLO, (2) a scheduler that adaptively computes per-link gate schedules, and (3) a complete system architecture deploying TAS. The system is implemented in OMNeT++ and evaluated using simulation to work under varying loads. The simulation of the design approaches deterministic behavior for high-priority traffic while maintaining low packet loss rates and latency even under extreme loads. Results demonstrate packet loss below 1% and latency under 40 ms for high-priority traffic even under loads up to 100,000 packets per second, compared to standard Wi-Fi configurations showing packet loss rates above 30%. This comes at the cost of throughput but represents a significant improvement.
