The Research And Application Of Mobile Agent Based Heterogeneous Data Integration System

The software agent technology is a kind of new calculation method to solve complex, dynamic, distributed intelligence application. Mobile agent is a special kind of agent which can save resources of the network effectively. With the rapid growth of the distributed application system in such respects as the scale, complexity, distributive space etc, the distributed application system has put forward higher demand for the network service.The research acts on the existing Heterogeneous Data Integration Prototype System (SORE) based on CORBA , but since CORBA has to use plenty of networks, which produces a model of good structure but poor running performance. In order to overcome the inherent disadvantages and provide better net running performance, reference to research accomplishment and the related technology nowadays,by combining Mobile Agent with CORBA,the advance edition named M-SORE is designed.And offer the networks of high performance , high usability service for the Heterogeneous Data Integration System.Experiment proof: I design and realize an advanced version to SORE named M-SORE .The M-SORE system can join with the original SORE system based on CORBA without seam, the stability of it is better, and it has good adaptability for complex network environment, when the network is unsteady or network bandwidth is below, the new system can be reliable, runs efficiently also.The paper includes 7 parts mainly: In the first part, it is introduced that the background of project, application prospect and meaning, my major job in the research course;Second part: Analyze the advantages and present research of Mobile Agent technology;Third part: Analyze IBM Aglet which is carried out as the core ofprogramming: mobility method and message method etc.;Forth part: Analyze SORE system,the meaning of adopting Mobile Agent, propose the architecture of advanced M-SORE with Mobile Agent;The part of 5th analyses the scheme of combining Mobile Agent and CORBA in detail, and discuss ARB bus architecture;The 6th part: M-SORE prototype system implements,introduces experiment procedure and print experiment result. The last part is conclusion and prospect. Evaluate the advantages and disadvantages of the new method, and point out future work in the part.
