METHOD FOR CONSTRUCTING A VIRTUAL ENVIRONMENT IN A P2P NETWORK OF THE DELAUNAY TYPE BY DYNAMIC GROUPING OF NODES, ASSISTANCE DEVICE AND RELATED EQUIPMENT

摘要

The invention relates to a method dedicated to the construction of a virtual environment in a peer-to-peer network of the Delaunay type for peer users associated with communication nodes (N8-N33) capable of mutually exchanging messages. The method comprises i) building node groups (G3) with neighbouring nodes of peer users having a maintenance cost higher than or equal to a selected threshold, and ii) calculating for each group (G3) the value of the surface occupied by the nodes as well as the co-ordinates of a virtual node (NV3) located at the centre of said surface, iii) transmitting to each node of a group (G3) at least the co-ordinates of the virtual node (NV3) of its group (G3) so that it communicates them to its neighbours which are not part of its group (G3) so that they now send to said virtual node (NV3) the messages addressed thereto, and iv) expanding the co-ordinates of each node in each group (G3) based on an expansion ratio particular to its group (G3) so as to reduce the density of this group (G3) proportionally to the corresponding expansion factor.
