Location based models for pervasive road networks

Context-aware mobile computing aims at designing applications that automatically adapt their behaviors to the available location information and the available nearby sensors and devices. This is done in order to fulfill tasks in a way that suits users' current context best. To achieve this, context representation and manipulation are important issues, so as to establish formal context models. In this paper, basic elements of context-aware systems are described with an emphasis on location information representations. Space models for location-based applications are presented. Considered realistic applications concern intelligent vehicles and pervasive road networks.
