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, said transmitter node and said first node being distinct, 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 a second set of data by the first node;
transmission of the first preamble as modified before the transmission of the first set of data; and
transmitting to the destination node or to a second node the 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.

13. 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, said transmitter node and said first node being distinct, 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.
