Modeling of End-to-End Resource Reservations in Component-Based Vehicular Embedded Systems

摘要

There is a plethora of models, techniques and tools that support model-and component-based software development of vehicular distributed embedded systems. However, a large majority of them have a limited or no support to model and specify end-to-end resource reservations on the software architectures of these systems. Resource reservations allow flexibility during the development and execution of such complex systems without jeopardizing their predictable behavior. As a result, several applications in the system that share the same hardware platform can be developed independently. In this paper we identify several requirements that any existing component model should fulfill in order to support the modeling of end-to-end resource reservations on the software architectures of such systems. As a proof of concept, we extend the Rubus Component Model (RCM) by fulfilling these requirements. RCM is used for the development of control functionality in vehicular embedded systems by several international companies. We also provide a technique to extract execution models from the software architectures of these systems with resource reservations. In order to show the usability of our technique, we model a vehicular distributed embedded system with the extended component model and extract the execution model from the software architecture augmented with end-to-end resource reservations.
