Zusammenfassung:	The invention relates to a method and a device for communication in an ad-hoc wireless network comprising a plurality of nodes, wherein a first node (10) is on board a vehicle. One or more messages sent by a second node (11) of the wireless network are received by the first node (10) on a control channel and each comprise an identifier of the second node. The integrity of the message(s) received is verified as well as the authenticity of the identifier of the second node (11). The first node then receives data informing same that an internet protocol access service is available, said data being received on a service channel and comprising an identifier of the transmitter of said data. The identifier of the second node is compared with the identifier of the transmitter of said data. If the identifiers match, the first node accesses the internet protocol service via the service channel.
