Claim:
1. A communication method in a wireless telecommunications network comprising wireless telecommunications nodes, the method comprising, during the transmission of a data block from a source node to a destination node, the method comprising the following steps implemented by a node, the node comprising a routing table in a memory of the node and being the source node or a relay node receiving and transmitting at least some segments of the block: selecting based on at least one content of the routing table of the node corresponding to the destination node and/or depending on states of the wireless telecommunications connections between the node and adjacent nodes of the node, a first adjacent node from among the adjacent nodes to the node, the node having stored a set of segments of the data block; determining an appropriate segment size for a transfer to the first adjacent node; reformatting at least one segment from the set of segment(s) based on the determined segment size; sending at least the reformatted segment to the first determined adjacent node; detecting a modification of the routing table and/or a modification of the state of the wireless telecommunications links between the node and the adjacent nodes, and following that detection; selecting a second adjacent node; stopping the transmission to the first adjacent node of the set of segments stored before the detection; determining an appropriate segment size for a transfer to the second determined adjacent node; reformatting at least one segment from the set of segments not yet transmitted to the first adjacent node based on the determined segment size for the transfer to the second adjacent node; and transmitting the at least one reformatted segment from the set of segments to the second adjacent node.
