Meshed radio network, network nodes, network coordinator and method for routing of data packets in a meshed radio network

摘要

In the case of a meshed radio network with an access point (ap) and located behind it, targets (nm, gw) for data packets of the access point (ap) is configured, a data packet with the destination address of one of the targets (nm, gw) outside of the radio network to be assumed. The said access point (ap) adjacent network node (a, b) contain, in lists (la, lb) in addition to or instead of the access point (ap), the destination addresses these targets (nm, gw). Due to the preference for a direct connection in the context of the destination selection, therefore, a data packet, which on such a target (for example, nm) is addressed in a first attempt at the than the target (nm) issuing access point (ap), and transmitted only when this experiment has failed, in a further experiment to another adjacent network node (for example, b) is forwarded.Thus, for each adjacent network node (a, b) a redundant path (from a to b and from b to a) to be indicated, so that in the case of a disorder of the connection of one of the network nodes (for example a) to the access point (ap) the data packets is not in the network node (a) accumulate.
