Aglet-Voyager Converter : An Approach for Mobile Agent Systems Integration

概要

Mobile agents are emerging as a new technology of building distributed systems. A number of mobile agent systems have been developed in recent years with different approaches and vary in the features they provide, such as mobility and securty. To enable these systems to work together in providing interoperability, we should provide a mechanism of mobile agent systems integration, especially, ones that enable the migration of mobile agents through different systems. In this paper, we introduce mobile agent systems integration based on converter approach and propose two strategies called dynamic conversion and autoconfiguration strategies based on the approach. To realize the proposed strategies, mapping between two systems, dynamic conversion mechanism that enables transparent movement between systems, and inter-agent messaging between systems based on the three-tier architecture are required. We implemented all these required capabilities and have chosen two well-known Java-based mobile agent systems called the Aglet(from IBM)and the Voyager(from ObjectSpace)as the implementation targets. The prototype system has successfully provided a transparent mobile agent migration from Aglet system to Voyager system based on the proposed dynamic conversion strategy.
