| 摘要 |
The invention relates to a communication method in a communication system comprising communication nodes forming a mesh network in which each node periodically transmits, via a shared transmission resource accessible to all the nodes, an adjacent network discovery message to said adjacent nodes, in order to detect the links that interconnect them, each node listening to the medium used to hold the shared transmission resource in order to determine whether said medium is free, nodes of a subassembly of the mesh network nodes being used as exclusive relays for the propagation of topological data distribution messages, characterized by the steps involving, for each node: detecting collisions with the medium while listening; the calculation of a metrics from the number of collisions detected; writing the metrics in a first field of the adjacent network detection message that the node transmits; receiving the adjacent network detection message originating from the adjacent nodes thereof; comparing the metrics thereof to the metrics of the adjacent nodes thereof; and adding a node to said subassembly depending on the result of the comparison. |
