Abstract: A method for estimating the time of flight between a first equipment item and a second equipment item includes the following steps carried out by the first equipment item: reception from the second equipment item of a transmission information item representing a time interval between the instant of reception of a message from the first equipment item and the instant of transmission by the second equipment item of a message including the transmission information item; and estimation of the time of flight between the first equipment item and the second equipment item by using the transmission information item. The time of flight can be used to determine the distance between two equipment items, for synchronizing two equipment items, or for detecting a movement of an equipment item.

Abstract: A method for processing a data packet exchanged between an item of client terminal equipment and an item of server equipment in a communication network, which the item of client equipment accesses via a first communication network, a first quality of service level being intended to be applied to the data packet. The method is implemented by an item of routing equipment of the first communication network and includes: detecting in the data packet at least one item of activation information of a second quality of service level to be applied to the data packet; obtaining a quality of service management rule according to the second quality of service level, associated with the item of activation information; applying the second quality of service level to the routing of the data packet according to the obtained rule, instead of the first quality of service level.

Abstract: A method, implemented by a first device, for establishing a radiofrequency communication with at least a second device is disclosed. The method includes a) transmission of a first message at a first transmission power, b) reception of at least one second message coming from at least the second device, the second message including data relating to a second transmission power of the second device, c) transmission of a third message at a third transmission power towards the second device, the third transmission power being determined on the basis of the second transmission power.

Abstract: A method for communicating an estimate of the location of at least one radio terminal to a connected object. The method is implemented by a mobile terminal and includes: receiving, at a given time, via at least one received radio signal, at least one identifier of a radio terminal; obtaining at least one estimate of the location of an identified radio terminal; associating, with each identifier, the location of the corresponding radio terminal and the time of reception of the corresponding radio signal; and broadcasting the aforementioned association via at least one radio signal to at least one connected object.

Abstract: A connected object, which is able to calculate its own position without using embedded elements specific for doing this. The connected object possesses a wireless receiver for receiving signals coming from a plurality of located terminals. The signals include location data for locating the located terminals. The connected object calculates a piece of geolocation information of its own position based on a plurality of location data coming from the various located terminals.

Abstract: A method for transmitting a data stream containing a second ordered sequence of numerical values, which sequence is determined from a first ordered sequence, a second succession of consecutive numerical values of the second sequence being obtained from a corresponding succession of consecutive numerical values of the first sequence. The method estimates a load value representative of a current load on the network, to determine, depending on the estimated value, a second succession to be transmitted in a predefined time interval following the current time, the second succession being a corresponding first succession of the first sequence or a succession modified by applying a selection law to the bits of the first succession and to transmit the second succession and, in case of transmission of a modified succession, a processing indicator signaling a succession modification.

Abstract: A signal generation method for generating a signal that is to be transmitted in a network of connected objects. The method includes: an obtaining step for obtaining a first signal conveying a stream of data acquired by a connected object of the network; a reception step for receiving a synchronization second signal including information providing a timestamp for the first signal; and a generation step for generating a third signal by using a reversible operation to combine the first signal and the synchronization second signal.
