Abstract

This paper presents a generic concept of location-based service as an abstraction for supporting the association between computational resources and location. The objective is to extend the advantages of service-based architectures to the development of location-based systems, thus providing a more open and extensible alternative to the vertical approaches typically used in this type of system. The novel AROUND architecture is proposed as an approach for supporting location-based services in the Internet environment. AROUND provides a service location infrastructure that allows applications to select services that are specifically associated with their current location. The architecture includes a flexible scope model that defines the association between services and location, and a service location infrastructure organised by spatial criteria and optimised for location-based queries. Based on a prototype implementation of this architecture, we have developed two case studies that illustrate the use of this approach for developing location-based systems. The overall results provide a valuable insight into the applicability of the architecture, and suggest that this model of location-based services can provide a useful approach for the development of a wide range of location-based applications.

Additional Information: This paper, the result of a collaboration with the University of Minho, addresses the problem of scalable support for location based service discovery by introducing a flexible model that defines the association between services and location and an infrastructure optimised for location-based queries. The work directly lead to 2 new research grants at Minho, both funded by the Portuguese Foundation for Science and Technology: LOCAL - Location contexts for location-based services and applications (Feb. 2004/ Jan. 2006, 46.092 ') and VADE - Value Added Environments for Dynamic Support to Location-Based Services in UMTS Networks (Feb. 2002/Out. 2004, 68.595 ').
