Joint routing and scheduling optimization algorithm for airborne time-sensitive networking

Abstract

The application of drones in rescue, exploration and other fields is becoming increasingly frequent. The existing bus tech-nology has low bandwidth performance, poor mounting capacity and poor interconnectivity, which cannot meet the in-creasingly large transmission needs of video, image, and control information in drone avionics systems, hindering the development of drone informatization and intelligence. Time-Sensitive Networking are a set of standards specified by the IEEE 802 working group, which provide deterministic connections for network devices while being compatible with tra-ditional Ethernet, and can be used to meet the information transmission requirements of Unmanned Aerial Vehicle avionics systems. This article proposes a novel optimization objective using a joint routing and scheduling optimization algorithm based on Integer Linear Programming, which can effectively solve the problems faced by bus technology in Unmanned Aerial Vehicle avionics systems. The simulation experiment results show that the proposed method performs well and reliably in terms of delay, and can provide good bandwidth performance.
