SMF-TYPE COMMUNICATION METHOD FOR A MANET NETWORK, NETWORK NODE AND MOBILE NETWORK WHICH IMPLEMENT THIS COMMUNICATION METHOD

摘要

A communication method of the SMF type for a network (1) of nodes including a multicast group. The method includes the steps, performed by a first node, of: determining (7a) a set of respective multipoint relays; determining (7b) the nodes for which the first node is a multipoint relay; determining (8) a routing table including identifiers of destination nodes and corresponding identifiers of next-hop nodes; receiving (10) a multicast packet sent from a sending node, where the first node is a multipoint relay; checking (22) if, for each node identifier of the multicast group, the entry in the routing table that includes a destination node identifier corresponding to the node identifier of the multicast group contains a next-hop node identifier that corresponds to the sending node, and if the counter contained in the multicast packet respects a relation with a limit; and determining (30; 42) whether to retransmit the multicast packet, on the basis of the outcome of the checking step.
