Abstract

An ad hoc network includes: a gateway connectable to a predetermined server via an external network; and a plurality of user nodes, constituting an ad hoc network along with the gateway and each transmitting data to the predetermined server via the gateway. Among the user nodes, at least one user node having a unit for establishing connection to the predetermined server via the external network can participate as a second gateway in the ad hoc network. Based on a predetermined rule, another user node among the plurality of user nodes selects the gateway or the second gateway and transmits data to the predetermined server.
