Integrating WSNs in an aircraft allows replacing or extending parts of wired communication for enhanced redundancy and to enable new applications. We propose and evaluate a mechanism based on the 6TiSCH protocol stack to differentiate traffic by priorities on the link layer. Proposed mechanism improves latency for time-critical avionic applications without compromising the performance of other traffic types. Analytical evaluation using queuing theory together with simulations in OMNeT++ demonstrate that up to three times reduction of the end-to-end delay for high-priority traffic is feasible.en6TiSCHAvionicQuality of ServiceQueuingReliabilityTSCHWireless Sensor NetworksConference Paper10.1109/ITNAC59571.2023.10368514Conference Paper
