摘要： Information related to DCs (31a to 31d) is specified from a GPS (35), a camera (36), and a sensor (37) of each of the DCs (31a to 31d), and physical information (D6), which is information indicating addition or deletion of each of actual nodes (32a to 32f) in the DCs, is obtained from image information and detection information of the specified DCs. Logical information (D8), which is information enabling determination of addition or deletion of each of the actual nodes (32a to 32f) in the DCs and peripheral nodes (32e and 32f) connected to the actual nodes, is obtained. Both the physical information (D6) and the logical information (D8) is combined, so that addition or deletion of each of the actual nodes (32a to 32f) in the DCs (31a to 31d) is estimated, and the estimated addition or deletion of each of the actual nodes in the DCs and a change in setting information of another actual node accompanying the addition or deletion of the actual nodes are reflected in node models (21a to 21f) of a communication NW model (21).

摘要： A network system (hybrid network (10)) includes a fixed representative node (101, 102), includes a plurality of terminal-accommodating networks (mobile networks (20, 21)) that transfers communication data between terminals (mobile terminals (401, 402)), an adjacent mobile node enabled to communicate with the fixed representative node (101, 102), and mobile nodes (201 to 204) different from the adjacent mobile node, and includes an ad hoc network 31 whose network topology dynamically changes depending on a locational relationship between the mobile nodes. When receiving communication data from the terminal (mobile terminal (401)) to the terminal (mobile terminal (402)), the fixed representative node (101) transfers the communication data to the mobile node (201) that is the adjacent mobile node. In the ad hoc network 31, the communication data is transferred to the mobile node (204), transmitted to the fixed representative node (102), and further transmitted to the terminal (mobile terminal (402)).
