The multipoint conference is expected to be one of the fundamental applications in ubiquitous environment, and hierarchical conference can be used well in this environment. The multipoint conference system using the endpoint mixing scheme causes the media data delay problem since the media data go through the hierarchical structure. In this paper, we propose an algorithm which minimizes the distance between terminals, and which considers the computing resource. When a new participant wants to join the ongoing hierarchical conference, our algorithm introduces a proper terminal in the conference and new participant"s terminal sends a call request to the introduced terminal which has the minimum distance from new participant"s terminal among the selected terminals with the computing resource consideration. As the experimental results with the proposed method, the hierarchical conference can be organized efficiently comparatively with the earlier schemes on the basis of media delay point of view because the average path distance between terminals can be reduced.
