Multi-model architecture for ITS software design improvements

ITS components are more and more software components, so ITS design research seems to join software engineering one. But if communication middlewares are well suited to standard software design, they become insufficient when software aims mobility, and especially ITS. We propose a solution based on a multi-model approach, able to simplify the work of ITS software designers, and to ensure communication between distributed components, however is the quality or availability of the network connection. We also present an application work, applying our multi-model approach to providing Internet access in trains.
