RESEARCH ON IMPROVED GRID RESOURCE DISCOVERY ALGORITHM BASED ON P2P NETWORK SYSTEM

摘要

At present, there are still many problems to be resolved in P2P network. For example, it is inefficient to organize and manage the grid resources, and there is no way to deal with resource updating brought by dynamic change of the grid resources, besides, there is no efficient strategy of discovering grid resources, etc. Mobile Agent, which has its own advantages such as mobility, distribution, concurrency and intelligent routing, should be effectively applied to the P2P network system. This paper firstly puts forward the network model of P2P system based on Mobile Agent, under which the resource discovery algorithm-GAMA (Genetic Algorithm Mobile Agent), which is integrated with genetic algorithms and Mobile Agent, has been put forward, then analyze the principle of integration, and show the explanations of integration process as well as more detailed description of the algorithm.
