An agent-oriented and service-oriented environment for deploying dynamic distributed systems

This paper presents JASE, a Java-based Agent-oriented and Service-oriented Environment for deploying dynamic distributed systems. JASE utilizes two important concepts in the field of distributed computing: the concept of services and remote programming with mobile agents. In JASE, mobile agents are used to support applications, and service interface agents are used to wrap services. Service interface agents can dynamically register their services in Service Server. Mobile agent locates a specific service interface agent by submitting requests to the Service Server with descriptions of required services. JASE uses XML to describe both service descriptions and the mobile agent's queries. JASE supports two kinds of communication facility: tuple space and asynchronous messages. In this paper, the design and implementation of JASE are described. An application shows the suitability and the effectiveness of the JASE and performance evaluation is also made. Finally, related work and some conclusions are given.
