Jini, Mobile Agent Technology And Its Network Applications

According to the nowadays large-scale network environment, how to improve the service and make it more flexible? This is a hot spot in current network research.Among different approaches, Mobile Agent has the potential to be applied to the new network generation, for a mobile agent can autonomously move from one host to another on heterogeneous net platforms, while exchanging information with the surroundings.Jini is a technology based on Java and RMI. Applications built with Jini is easy to be transplanted and managed, and can join the net at anytime. Due to these advantages, Jini is chosen for the best technology to realize the mobile agent system.Based on the Jini specification, this paper put forward a mobile agent structure -- JMAgent. It defines the models of location, travel and communication about the agents. This paper also discussed about how to deal with the failure of the network. Mobile agents developed in this way have the abilities of compatibility, flexibility and can be upgraded easily.As to the modules and designs of the classes, this paper focused on the aspects of the agents' travel and communication, which are two key parts of the JMAgent development.
