Abstract

We show how to use Web Services standards for propagation, discovery, and composition of location-based services in mobile environments. To achieve semantic interoperability we express location information in XML using context-specific ontologies. The achieved interoperability allows for context-aware on-demand service composition making the composite service highly available and resilient to environmental dynamics and uncertainties.
