A process for the time slot - based transmission of data packets in a wireless meshed network

摘要

The invention relates to a method for time slot - based transmission of data packets in a wireless meshed network with a plurality of nodes (1, 2,.., 5). In the method according to the invention, in a step a) for in the network data packets to be transmitted, one or more graph (g, g '') with respective graph - identities (gi, gi'') is formed. The graph (g, g '') specifying in this case possible transmission paths of data packets by means of a wireless data to the left (l1, l2,.., l7) between adjacent node to a destination node, wherein each data packet in a function of the destination node of the packet a corresponding curve - identity (gi, gi'') contains. In a step b) of the process, on one or more radio channels in cyclically repeated time frame (f) reserved one or more time slots, which in each case a node (1, 2,.., 5) with an associated data link (l1, l2,.., l7) between the node and is associated with one other node. In a step c), in case of or before the occurrence of a time slot (s0, s1,.., s19) of the time slot assigned node (1, 2,.., 5) according to any one of the data packet to be transmitted, the graph - identity (gi, gi '') a graph (g, g'') corresponds to the node associated with the data link (l1, l2,.., l7) comprises. The method is distinguished in that respect in that the to the node (1, 2,.., 5) data belonging to the left (l1, l2,.., l7) at least partially, in each case, one or more graph - identities (gi, gi '') are assigned and a data transmission in the corresponding time slot takes place only when a in step c) aufgefundenes data packet contains a graph - identity with a graph - identity (gi, gi'') of the associated data of the left (l1, l2,.., l7) coincides.
