The Research And Application Of Distributed Data Query Based On Mobile Agent

With the large number of users and explosive information on network, the traditional distributed data query technique is ineffective and blocks the development of network. So it promotes people to research and develop a new and more effective distributed data query model.Mobile agent technology is a new kind of technology of distributed computation. It is a combination of distributed technique and agent technique. Mobile agents involves many technology domains, such as computer networks, distributed systems under the Internet environment for its characteristic of moving, autonomy and collaboration, and manifested great application perspectives and advantages.This thesis mainly explores how to apply mobile agent to distributed data query area, and makes some elementary attempt on this problem. This thesis firstly analyses the architecture of traditional distributed data query technique, introduces the conception of mobile agent, the architecture and technique of mobile agent, describes in detail the software development method based on mobile agent technology, then designs a model of mobile agent based distributed data query system by combining the mobile agent technique and distributed data query technique, and illustrates the required techniques to implement this model. In the end, this thesis introduces the design and implementation of a mobile agent based distributed data query prototype system: MABDDQS.
