Multi Sensor Cross Layer Integrity Framework: Concept For Information Reliability Assessment Of Safety Critical Systems

Kurzfassung

The past few decades have seen an unprecedented rise in technological development, that led to exponentially increasing computational capabilities and the possibility of relying on complex sensor systems to automatically monitor safety-critical applications. These technological advancements have provided enormous advantages, but they are also responsible for an increased reliance on technology, raising the importance of assessing and improving the integrity of sensors that are ever more frequently used on various systems. Due to the multitude of systems that relies on the information provided by sensors, with various requirements and specific characteristics, the challenge of designing a standard solution capable of guaranteeing the integrity of a generic monitoring system is unmet. In the literature, it has been found specific solutions for specific problems, with most of the integrity monitoring methods devoted to positional integrity in the navigation domain (Costa de Oliveira et al., 2022; Jing et al., 2022). Considering this gap in the field, the development of a multi-sensor integrity monitoring strategy, flexible to work with different sensor types, and capable of meeting the integrity requirements for safety-critical scenarios, would be highly desirable. The concept proposed here is a step towards that realization.
