AmbieAgents: a scalable infrastructure for mobile and context-aware information services

Context-aware information systems for mobile users have to cope with a variety of requirements in order to be able to provide an added value that goes beyond simply location-based services. The EU-IST AmbieSense project has developed a reference architecture and implemented demonstrators that meet a number of these requirements. In this paper we present AmbieAgents, an agent-based infrastructure for context-based information delivery for mobile users. We describe the overall AmbieSense system architecture and particularly the agent-system and its main features. As the AmbieSense system was demonstrated in a real world scenario at the Oslo international airport, we also give an account of our experiences from user tests executed during the demonstration.
