COMMUNICATION SIGNAL TRANSMISSION METHOD

摘要

The invention relates to a method for transmitting a communication signal in a communication network including a plurality of nodes alternately corresponding to sleep periods and wake periods, a transmitting node ensuring that the transmission of data to a destination node is preceded by a step comprising the transmission of an initial preamble. According to the invention, the method includes at least one initial preamble transmission relay through a node adjacent to the transmitting node, whereby a relay corresponds to the transmission of a preamble formed from the preamble transmitted during the previous relay, the preamble transmitted at the time of the first relay is formed from the initial preamble and said at least one relay is ensured until the data destination node detects the transmitted preamble.
