Improvement of strong migration method to manage multithreaded agents and implementation of mechanisms for sharing information of agents in AgentSphere

Abstract

We the authors of this study use mobile agents with capability of strong migration to develop AgentSphere, a platform for an autonomous parallel and distributed processing system that significantly reduces loads of the complex execution control for its users. We have successfully executed the strong migration of agents on JVM by converting their source codes. However, there has been an issue that the overhead becomes larger accompanied by migration such as when saving or restoring the data in the stack area, or when migration to the resuming position occurs during the execution of the program. In order to improve this issue, a new mechanism for the strong migration using JavaFlow was built. We report that we also built the information sharing mechanism using a distributed hash table so both the user and the system can share information of each agent effectively.
