PROBLEM TO BE SOLVED: To achieve wireless LAN communication in which data can be surely delivered to a transmission destination even when transmission is delayed at a place where an existent communication infrastructure is not provided. SOLUTION: A multi-hop network system 1 is constituted of a plurality of nodes 2 and a center server 3 and transfers message data from one node 2 to the center server 3. The nodes 2 include nodes moving within a predetermined area. Each of the nodes 2 selects, at least between message data received from the other nodes 2 and message data generated by the node 2 itself, one or more pieces of message data so as to be smaller than or equal to a predetermined size and when there are two or more pieces of selected message data, these pieces of message data are coupled to define the selected one piece of data or the coupled two or more pieces of data as target data. In a case where the node 2 itself is communicable with the center server 3, the node 2 transmits the target data to the center server 3 but in a case where the node 2 is uncommunicable with the center server 3, the node 2 transmits the target data to the other nodes 2.
