Abstract
Provided are methods for receiving and transmitting a communication signal by radio channel and corresponding devices and computer programs. A plurality of nodes alternately comply with sleep periods and wake periods, and a transmitter node precedes transmission of data to a recipient node with a step of transmitting a preamble of a length at least equal to a sleep period of the recipient node, wherein at least two transmission channels has been defined between the nodes with a view to the transmission of the preamble. The method includes selecting from the plurality of channels at least one channel for listening to the preamble, called a current channel; and deciding to the change the listening channel on detection of at least one triggering event likely to affect predetermined operational constraints of the receiver node.
