Abstract
A method for operating an ad-hoc network for the wireless data transmission of synchronous and asynchronous messages synchronizes the transmitters and receivers of neighboring nodes on a transmission path using cyclically transmitted identifiers, whose intervals define a time frame. The nodes of the transmission path reserve time slots within the time frame for the transmission of data packets of a virtual connection that are to transmitted synchronously. A start signal is transmitted at the stars of the synchronous transmission of a virtual connection, the data packets are then transmitted in the previously defined time slots and the synchronous transmission is concluded by a stop signal. Free time slots in the nodes are filled with data packets that can be transmitted asynchronously, the packets being read from an output buffer memory of the node.
