Resumo:
The advancements in portable devices, wireless communication and positioning technologies
have enabled one of the most promising mobile services: location-based systems (LBS),
which provide information to mobile users according to their geographic locations. Typical
examples of such services include area maps, navegation, local weather, traffic condition,
and tour guide, etc.
Existing location-aware applications and systems typically provide services for a specific
application domain. However, different types of location-based information from distinct
domains could be relevant to the user context such as the set of services mentioned above.
Taking these aspects into account, this paper presents an infrastructure to develop
location-aware applications providing personalized services about several domains. This
issue have been addressed by developing a scalable and extensible architecture, and providing
an API to access services. A case of estudy for the weather domain was implemented
demonstrating the infrastructure support to applications development involving several domains.
