Abstract In MAS environment, some key techniques are needed to realize interaction and cooperation of mobile Agents. In this paper, genetic algorithm is introduced to assign Agent to a suitable node, improved the coordination efficiency of Agents. An Agent communication language—knowledge query and manipulation language is analyzed and an Agent communication model is established based on knowledge query and manipulation language. Also, an effective way to solve Agent location tracing and invalidated communicating during Agent roaming among network nodes is provided.
Key words multi agent system; mobile agent; knowledge query and manipulation language; communication model; cooperation
