| 摘要 |
<p>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 ail 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.</p> |
