Consistency of shared information stored in each terminal is maintained while reducing the processing load in each terminal. A plurality of terminals are connected to each other via a network, an area control group is formed of the terminals, and each terminal belongs to one or more control groups. The area control group selects one or more terminals among the terminals constituting the area control group, as a relay terminal for relaying shared information in the area control group, and ensures consistency of shared information stored in each terminal while reducing the processing load in each terminal by updating and controlling shared information via the relay terminal. |
