Zusammenfassung:	A communication method of the OLSR type for a network (1) of nodes (2), including the steps, performed by a node, of: determining (72, 78, 22-54) a respective set of multipoint relays, a respective routing table and a respective role between cluster head (CH) and affiliated node (ST). The step of creating a routing table includes: if the node is a cluster head, storing (78) destination addresses respectively equal to the addresses of the cluster heads different from the node and the addresses of the nodes affiliated with node,- if the node is an affiliated node, storing (78) destination addresses respectively equal to the address of the cluster head to which the node is affiliated and the addresses of the nodes affiliated to the latter cluster head. The method further includes the step of the node sending (109a-109b, 111a-111b, 124, 126, 144, 146), a data packet having a respective destination address and a respective next-hop address, the latter address being dependent on the role of the node, the content of the node' s routing table and the destination address of the data packet.
