A Component-based Software Infrastructure for Contextual Transportation Applications
Résumé
In the transportation domain, software applications running on mobile devices are more and more needed. These applications have strong requirements to address: heterogeneity and limited ressources of wireless networks and mobile devices, networked communications, security, discovery of services, deployment on mobile devices, etc. These requirements are similar to those of any ubiquitous computing application. In this paper, we present a component-based software infrastructure to design, discover, deploy, and execute ubiquitous computing contextual services, i.e. applications providing services to mobile end-users and only available from particular place. Services are designed as assemblies of software components that are dynamically discovered according to end-users' physical location and device capabilities, and automatically deployed on it. Our software infrastructure and an example of service in the field of transportation have been implemented on top of the OMG's CORBA Component Model (CCM) and the OpenCCM open source platform.
