Abstract:
1. A method for determining a sequence of access to a communications network by a plurality of nodes in a broadcasting of a content by a transmitter node to a set of receiver nodes, at least one receiver node having to receive said content by a relay receiver node, wherein said method comprises the following steps implemented by a manager device: for each receiver node, determining at least one filial link with at least one other node, a filial link existing between two nodes when a direct communication between the two nodes is possible; determining a hierarchical tree whose root is the transmitter node, on the basis of a selection of a set of determined filial links, as a function of at least one rule of diversity, said hierarchical tree defining at least one relay receiver node and enabling the reception of the content by the set of receiver nodes; and determining said sequence of access from the hierarchical tree so that, between access by said relay receiver node or nodes and access by the receiver node or nodes linked to it or to them by the filial links of said hierarchical tree, the sequence of access provides that at least one of said plurality of nodes will access the communications network.
