Abstract

The proliferation of mobile devices has refocused interest on location-information exploiting applications. The most prominent problems are the support of devices with widely varying computing and user interface capabilities and a programming model, which promotes the development of location-based services. The article presents the concepts and implementation of MUSA-Shadow, which addresses both issues through a service infrastructure that provides high-level programming abstraction for the development of location-based applications. Furthermore the system introduces novel concepts for user/service interaction via adaptable event graphs and implicit location information via mobile agents.
