  • Publication number: 20240340770
    Abstract: 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)).
