Fault-tolerant Lightweight High Level Architecture

This research presents a fault-tolerant distributed Run-Time Infrastructure (RTI) using the High-Level Architecture (HLA) standard, emphasizing its importance for safetycritical use cases such as automotive systems. In this context, HLA serves as an enabler for hardware-in-the-loop testing, particularly vehicle-in-the-loop testing. Ensuring system reliability, managing real-time responses, facilitating seamless integration and interoperability of various components, effectively handling potential component failures, and maintaining the scalability of complex systems is paramount. Furthermore, the ability to comply with stringent safety regulations also underlines the necessity for safety mechanisms. These safety measures are crucial in protecting users and ensuring dependable system performance, particularly in safety-critical automotive applications where user safety is paramount. The study develops a fault-tolerant distributed RTI, validates it with an automotive use case, and provides a comparative assessment of centralized and distributed HLA implementations. The findings offer insight into large-scale distributed simulations' efficiency, dependability, and safety in various safety-critical applications.
