A method for synchronization and communication in a multi-hop network includes: transmitting a synchronization signal by a central node or a previously synchronized node, with a beacon slot assigned a beacon and the hop count value of the transmitting node transmitted in the frame of the synchronization signal, and, for all previously synchronized neighbor nodes of the transmitting node transmitting respective beacon slots and the hop count values in the frame of the synchronization; receiving by a first node the synchronization signal and the data transmitted in connection therewith; synchronizing the first node to the synchronization signal; detecting by the first node its neighbors and their respective beacon slot assignment and hop count values; determining the predecessor of the first node in the network by the first node in dependence of given criteria; storing by the first node the data received with the synchronization signal and data received in connection therewith and determined therefrom; and repetition the foregoing steps until synchronization of all the nodes.
