Abstract


The 21st century is the century of mankind towards the information society, the network era, the era of substantive progress in the construction of ultra-high-speed information highway and into the application. Network computing environment is also being changed to the Client / Network Client / Server Development, and is being developed to Client / Virtual Environment. In this case, there has been a wide range of mobile computing model, such as the client / server model, the code that need to box mode, but these mobile computing model with its inherent limitations, such as the remote host or server can only communication asynchronous way, waiting for a long time, serious bandwidth waste, for a particular task, only serial processing. Mobile Agent from the artificial intelligence is the product of the combination of artificial intelligence technology and network technology, distributed computing or network computing has many unique advantages. Such as reducing the amount of traffic on the network: asynchronous autonomous operation; Agent of intelligent features to autonomous decision moving target, help load balancing, but also can reduce the users to browse or search the judgment; reduce the complexity of distributed systems . These characteristics have contributed to the Mobile Agent technology in a large number of applications in a distributed computing environment, such as network management, e-commerce, information retrieval. Mobile Agent computing model will become the mainstream model of the future of network computing. Agent theoretical study on the basis of existing (as Agent theoretical model, structure), the design of a Mobile Agent System architecture model, a Mobile Agent system is divided into four main parts, Mobile Agent environment, mobile Agent, docked server, information service center. And focuses on the two functional modules - communication module and migration mechanism. And on this basis a new information system based on Mobile Agent discovery environment. The vast majority of traditional search engines are based on the client / server model of online search mode, and the server backend maintain predefined database of vast amounts of information, there are too much dependence on the structure of the letter of Kai, database and network, and The search engines do not support asynchronous transfer, therefore an urgent need for a new type of a personalized, intelligent information discovery systems. Personal Intelligent Agent to search for information submitted to the Mobile Agent, Mobile Agent information in accordance with the travel schedule to move to the destination with the above information service Agent interaction, Information Service Agent based on the Mobile Agent to carry to the information in the information database to retrieve the corresponding information, and handed it to the mobile Agent, of mobile Agent or move to the next target or back to the original host. Such an Agent society can provide users with more efficient information services, more affinity to the user therefore has a broad application prospects.
