Design of Directory Facilitator for Agent-Based Service Discovery in Ubiquitous Computing Environments

As the ubiquitous computing is rapidly changing, the research on agent technologies is constantly being conducted. In a multi-agent system environment, each agent is registered in directory facilitator in a fixed from for service it provides, and gains a set-vice function capable of modifying and deleting the set-vice. Other agents may inquire about a service they want and receive necessary information on the service. By using this directory facilitator. the user can retrieve the most appropriate service. In this paper. we propose an efficient directory facilitator architecture that can improve the existing agent-based service discovery.
