Nowadays there are many applications that users can benefit from on their handheld devices: localization, navigation, e-commerce, social networks and many others. Such capabilities are reaching our vehicles, offering drivers help for driving safely and more efficiently, thanks to the numerous services provided by applications on their devices. To simplify application assembly and reactivity according to transportation constraints (lack of communication infrastructure, high mobility...), we propose a framework that hosts multiple applications at once, offering at the same time management functions for context-awareness. Our framework is intended for mobile devices such as smartphones or in-car devices, which can range from stationary to highly mobile. We propose a service-oriented architecture able to compose applications out of services. This makes our framework flexible and allows for easier adaptation to context changes through the use of a Context Manager for all services (instead of having each service or application monitor the context). In this paper we present our proposition as well as some initial evaluations.
