Paper Abstract:
|
Location-based applications and services will get increasingly important for mobile users of the future. They take into account a mobile user's current location and provide a location-dependent output. Often, location-based applications have to deal with raw location data of specific positioning systems (e.g. GPS) and perform further processing to get an appro-priate representation. In this paper, we present a platform, which hides specific details of positioning systems and pro-vides a uniform output containing both physical as well as semantic information. With the help of our platform, an appli-cation developer can concentrate on the application-specific details and has not to deal with position capturing and map-ping. The corresponding infrastructure reflects a location domain model especially designed to cover the needs of mobile users. The domain model contains logical links and allows the expression of semantic relations between locations. As our infrastructure is self-organizing, it is flexible and easy to extend. |
