<p>To enable one-to-many or many-to-many unique information communication to be effectively performed. A belonging area determining means (1b) equally divides a relative coordinate system, the origin point of which is the position of a computer (1), into a plurality of areas in accordance with directions from the origin point, and determines, based on the relative coordinates of nodes, the areas to which the nodes belong. Thereafter, when an instruction of executing a unique information group communication is entered, a unique information group communication executing means (1d) executes a transmission of a message including unique data to the nodes an equal number of times per predetermined reference time period for each area in turn.</p> |
