Abstract

A method for making safety mechanisms available in wireless mesh networks which have a plurality of nodes that are interconnected by multi-hop communication in a wireless network meshed by mesh routing in the MAC layer, every node being active as a router to forward the data traffic of the other nodes. At least two differentiated levels of confidence are defined by a type of protection (ToP) the value of which represents a specific level of confidence for the nodes and data packets, the data packets being labeled with a ToP value in the mesh header, and at least one ToP value being allocated to the participating nodes, the nodes forwarding the data packet in the mesh network using the ToP values of the node and of the data packet if this ToP value combination is admissible in the node.
