Furthermore, complementing existing wired systems with wireless sensors adds redundancy and fault tolerance. Although many applications are already envisioned under the umbrella of Wireless Avionics Intra-Communications (WAIC), finding a suitable communication technology remains challenging due to diverse Quality of Service (QoS) requirements. In this work we discuss challenges associated with the deployment of an in-cabin wireless sensor network (WSN) using different radio bands and propose a solution based on the IPv6 over the TSCH mode of IEEE 802.15.4 (6TiSCH) protocol stack. By extending the latter with cross-layer as well as layer-specific improvements, different challenges in terms of bounded end-to-end delay and high packet delivery ratio are addressed. The solution is validated in simulations using OMNeT++, showing the feasibility of meeting stringent QoS requirements for in-cabin WSNs.enquality of servicereliabilityend-to-end delayavionics6TiSCHwireless sensor networksComputer Science, Information and General Works::003: Systems Theory::003.5: Communication and ControlComputer Science, Information and General Works::004: Computer SciencesConference Paper10.1109/mswim67937.2025.11308978Conference Paper
