Abstract
In multi-agent system, it is very popular to process with Multipoint-to-Multipoint communication. On the other hand, communicating multiple agents with one agent which has central role makes it possible to exist the system which doesn't require so complex deduction mechanism. We propose a hirrarchical multi-agent system. In this system, agents on the host in the hierarchical network comunicate with each other to transport lots of data. Moreover we inplemented this system actually and examined the effect of this dynamic restructuring function. Consequently, we got a good result.
