Mobile Software Agents for Location-based Systems

As mobile computing matures, location-awareness as part of context-awareness gains more attention - especially, location-aware services for mobile users. This paper concentrates on the software engineering issues of location-aware services and presents Mobile Shadow as an successful example of a design and an implementation of a scalable, fault tolerant, and component-based service infrastructure for location-aware services. The paper presents the basic concepts used in Mobile Shadow, the requirements, and the resulting component architecture.
