20110110292 | METHOD OF TRANSMITTING A COMMUNICATIONS SIGNAL - A method is provided for sending a communications signal in a communications network having a plurality of nodes assuming alternating sleeping and waking states and in which a sender node executes a step of sending an initial preamble, prior to sending data to a destination node. The method includes at least one operation of a neighbor node of the sender node relaying the initial preamble, where a relaying operation corresponds to sending a preamble formed from the preamble sent during the preceding relaying operation, the preamble sent during the first relaying operation being formed from the initial preamble, and the at least one relaying operation continuing until the destination node for the data detects the sent preamble. | 05-12-2011 |
20140074929 | PROTECTION AGAINST THE DETECTION OF ALERT SIGNALS - A method of communicating between at least one event detector sensor and a collector of event detection data transmitted by the sensor in the form of an event signalling message whose modulation is defined by at least one spreading code. The method comprises the steps implemented by the sensor of, upon detection of an event, generation of data of event detection, of reception of a synchronization message emitted by the collector, the synchronization message comprising a seed for a pseudo-random generation of at least one spreading code and of pseudo-random generation of at least one spreading code on the basis of the seed. The method furthermore comprises a step of emitting an event signalling message whose modulation is defined by the at least one spreading code generated randomly, the event signalling message comprising the event detection data. | 03-13-2014 |
20140233733 | METHOD OF PROCESSING A DATA PACKET BEFORE TRANSMISSION OVER A RADIO COMMUNICATIONS NETWORK, A METHOD OF PROCESSING A RECEIVED DATA PACKET, AND ASSOCIATED DEVICES AND SYSTEMS - A method for processing a data packet before transmission over a radio communications network as a succession of waveforms transmitted at positions defined by hopping codes, which are time positions or frequency positions. The packet is transmitted over a communications channel of the network by a transmitter node to a destination node. The method includes the following steps performed for each bit of the data packet to be transmitted, referred to as the current bit: calculating a hopping code at least as a function of the value of the current bit and of an encryption key generated by a pseudo-random generator, the encryption key having size greater than the maximum size of a data packet transmitted over the channel; and causing a waveform to be transmitted at the position defined by the calculated hopping code, the transmitted waveform being identical regardless of the value of the current bit. | 08-21-2014 |
20150078228 | Method for Processing the Reception of a Communication Signal by Radio Channel, and Associated Method for Processing the Transmission, Devices and Computer Programs - 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. | 03-19-2015 |

20120244896 | METHOD FOR TRANSMITTING A COMMUNICATION SIGNAL - 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. | 09-27-2012 |
