1. Method for the operation of an ad hoc network for wireless transmission of synchronous and asynchronous messages, whereby the network is composed of network nodes that are distributed in any desired manner, each of which has a receiving device having an input controller, a switching station, and a transmitting device having an output controller, whereby transmission paths for logical connections to be transmitted from a starting node to a target node are established by way of intermediate nodes, according to a routing method, and whereby the nodes administer local address and control data (LCI) that are assigned to the logical connections and are reported to the preceding node of the transmission path, characterized in that that the transmitting and receiving devices of adjacent nodes of a transmission path are synchronized, using cyclically transmitted identifiers, the distances between which define a time frame, that the nodes of the transmission path reserve time slots within the time frame, for the transmission of data packets of a logical connection to be transmitted synchronously, whereby a start signal is sent at the beginning of a synchronous transmission of the logical connection, subsequently the data packets are transmitted in the previously determined time slots, and the synchronous transmission is concluded with a stop signal, and that free time slots in the nodes are filled up with data packets transmitted asynchronously, which are read out from an output buffer of the node.
