Infraestrutura para o desenvolvimento de aplicações baseadas em localização e orientadas a domínios.

Abstract

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.
