Computer Theory And Application Of Mobile Agent

Agent, multi-agent system and mobile agent are advanced study field for AI. Based on inherent autonomy and self-adaptability of Agent, it has a series of study fruit in constructing complex system. Mobile agent based means may become the basis of calculation in network age. But it has no good ways for mobile computing. On fixed and mobile computer equipment based extensive network, the goal of this paper is to construct a new system structure, enhance the live ability and autonomy, and give a found for designing mobile computer model and system.With stupendous development of computer network, it is m :>or extensive and immanence especially based on the technique extension of wireless communication network and tridimensional network communication. Network connection isn't affixation of computer any more, and becomes necessary. Connection doesn't tightly relate to physics location, and becomes a concept independence of location. The role of global computer network is change from ordinary communication base to computer lat supported by calculating service with rapid change. Network scale increasing and diversified form don't advance computer ability. Software, as the soul, far lags behind in the development of hardware. How to construct software infrastructure, providing more and excellent information service neatly and handily, becomes a new challenge. It forces research work to provide the solution by rethinking the comprehensive characteristic of the new computing platform, because software calculate infrastructure doesn't catch up with the development of communication infrastructure. At present, two kinds calculate cares about mobile agent: mobile computingand mobile computation. The former cares about the calculation that carries on mobiles device based on wireless network. The later cares about the movement program based on WEB, e.g. agent computing. Mobile computing is a good pattern, and it can solve some problem in distributed calculate, e.g. location concept, instability of the communication service quality, dynamic variety of configure, out of observing for failure.With the development of distributing target's technology, network technology, especially WWW, software system inclines to network calculates and action-oriented parts. The agent-oriented soft project is based on object-oriented and distributed computer technology to construct soft system, and it endows calculate entity more agility, independence and character of socialization.Among them the most representative one is mobile agent system. On such new computer pattern, a lot of experimental products have appeared, e.g. IBM's Aglets, General Magic's Telescripts and Odyssey, Mitsubishi Electric's Concordia, Stuttgart university's Mole, Kaiserslautern university's Ara, Open Group'sMOA, etc. They each have their characteristic, but all support a common characteristic: agent (or object) can resume after moving. Each product set up one common use system platform, and supports the specific function demand service of the system more or less.
