A Unified Architecture for Supporting Direct Tag-Based and Indirect Network-Based Resource Discovery

Discovering and integrating ambient computational resources is a central topic in AmI. There are two major existing approaches: indirect network-based resource selection and direct tag-based resource identification. We motivate the need to integrate the two approaches through a scenario. We then present an architecture for a pluggable discovery system called UbiDisco. We demonstrate how UbiDisco implements a seamless integration of the two approaches at user interaction level through a framework for implementing discovery actions.
