Research On Agent Cooperation Technology Based On CNP

With the computer network technology, computer communications technology, distributed parallel processing technology development, Agent and Multi-Agent Systems (MAS) has become hot issues on which the Distributed Artificial Intelligence (DAI) research and caused more and more attention, but also been applied more and more widely. MAS has higher intelligent and stronger ability of solving than a single Agent, through multiple Agent cooperation to solute complex problems has become an important means. Cooperation among Agents is the core issue of MAS's research, and cooperation can improve the performance of the whole system, enhance system problem-solving skills. Perfect mechanism is the basis of Agent's cooperation.Papers research the technology of Agent cooperation based on CNP. First, papers introduce and discuss the basic theories of Agent and MAS, analyze the communication and cooperation theory of MAS, research various cooperate approaches. Focus is the cooperation based on CNP, and analyzing several inadequate.Then Papers analyze the FIPA CNP, which is successfully improve and widely used, and sum up the two issues which are still exist: one is frequent communication; the other is waste of resources. A large number of foreign study results show that the analysis of historical task can effectively improve the reliability of the system, reduce the communication cost of the whole system, and reduce the consumption of resources. Through introducing and combining the Trust, Active and Grouping papers reduce the frequent communication. And through adding a model in agent designing papers reduce the waste of resources. Then papers discuss, analyze and solve new problems, perfect the bidding process. After describing workflow of the new CNP, papers set up a complete model on CNP cooperation. The last is summary and next work in the future.
