| 摘要 |
The invention relates to a method for operating a wireless mesh data network with multiple nodes (A, B, C, D, F, G, S), wherein data frames are transmitted from a source node (SN) via one or more intermediate nodes (IN) to a destination node (DN), wherein the source node (SN), the one or more intermediate nodes (IN), and the destination node (DN) constitute network nodes (MN) of the data network, wherein during transmission of a data frame, at least some of the network nodes (MN) which receive the data frame, using a precursor list for the destination nodes (DN) which is assigned to the destination nodes (DN) of the data frame, check whether the network node (MN) sending the data frame is in the precursor list, wherein in the case of a positive result, the data frame is transmitted to a further network node (MN), and in the case of a negative result, the data frame is thrown out or processed by an error recovery routine.
