Enabling Quality-of-Service for avionic wireless sensor networks in ISM and WAIC band using multi-layer improvements to 6TiSCH

Replacing traditional wired connections with wireless systems on the aircraft can significantly reduce weight and fuel consumption. 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.
