METHOD FOR TRANSMITTING A COMMUNICATION SIGNAL
First Claim
1. A method of transmission of data in a network including a plurality of nodes alternating sleeping periods and waking periods asynchronously with respect to each other, said method being implemented by a first node wherein it comprises the following steps:
- receiving a first preamble transmitted by at least one transmitter node, the first preamble including at least one first set of information relating to transmission by the transmitter node of a first set of data to a destination node;
modification of the first preamble by adding a second set of information relating to the transmission of the second set of data by the first node;
transmission of the first preamble as modified before the transmission of the first set of data andtransmitting to the destination node or to a second node a second set of data after transmission of the first set of data.

Abstract
A data transmitter is provided for transmitting data that makes it possible for nodes, relaying the preamble transmitted by a transmitter node, to also transmit data to a single destination node without, in turn, transmitting another preamble. In a network comprising a plurality of nodes that alternately observe sleeping and waking periods in an asynchronous manner relative to each other, a node receives a first preamble that is transmitted by at least one transmitter node. The first preamble comprises at least one first set of information related to transmission, by the transmitter node, of a first data set to a destination node. The adjacent node transmits a second data set to the destination node or to another node from the transmission of the first data set.

5. A data transmission device adapted to be integrated into a network including a plurality of nodes alternating sleeping periods with waking periods asynchronously with respect to each other, comprising:
-
a receiver adapted to receive a first preamble transmitted by at least one transmitter node, the first preamble including at least one first set of information relating to transmission by the transmitter node of a first set of data to a destination node; modification element adapted to modify the first preamble by adding a second set of information relating to the transmission of the second set of data by the first node; a transmitter adapted to transmit the first preamble as modified before the transmission of the first set of data and a transmitter adapted to transmit to the destination node or to a second node a second set of data after transmission of the first set of data.
