Supporting Early Modeling and End-to-end Timing Analysis of Vehicular Distributed Real-Time Applications

Abstract

REACTION 2012. 1st International workshop on Real-time and distributed computing in emerging applications. December 4th, 2012, San Juan, Puerto Rico.The current model- and component-based development approaches for automotive distributed real-time systems have non-existing, or limited, support for modeling network traffic originating from outside the vehicle, i.e., vehicle-tovehicle, vehicle-to-infrastructure, and cloud-based applications. We present novel modeling and analysis techniques to allow early end-to-end timing analysis of distributed applications based on their models and simple models of network traffic that originates from outside of the model. As a proof of concept, we implement these techniques in the existing industrial tool suite Rubus- ICE which is used for the development of software for vehicular embedded systems by several international companies. We also conduct an application-case study to validate our techniques.This work is supported by the Swedish Knowledge Foundation (KKS) within the project FEMMVA.
