Abstract: A method for setting a security level of wireless sensors communicating with a switch, the method including in a security device linked to the switch: collecting data frames sent from the wireless sensors to the switch and creating a dataset containing the collected data frames; identifying patterns associated with the wireless sensors from the collected data frames, each pattern being based on a periodic time interval for sending two consecutive data frames by a wireless sensor or based on a number of data frames sent by a wireless sensor during a time interval of usage; introducing simulated traffic anomalies in the dataset with respect to the traffic patterns; randomizing the dataset and dividing the randomized dataset in a training dataset and in a testing dataset, wherein the training dataset contains more data frames than the testing dataset; training, by using the training dataset, a machine learning model configured for detecting traffic anomalies, and validating the machine learning model if the t

Abstract: A method for managing mobility of communication devices, wherein a gateway manager is connected to a set of gateways, each gateway being paired with at least one communication device through wireless links and each communication device being paired to only one gateway, wherein a first database linked to the gateway manager includes primary vectors containing an identifier of a gateway, an identifierof communication device and quality metrics, the method including: the gateways storing, for each received message sent from communication devices, a secondary vectorincluding an identifier of the communication device, a timestamp and quality metrics pertaining to the radio link between the gateway and the communication device, the gateway manager collecting the secondary vectors from all the gateways and storing the collected secondary vectors in correspondence respectively with identifiers of the gateways in a manager database, the gateway manager selecting, based on the quality metrics, a secondary vector among

Abstract: A method for addressing a slave device in a network system comprising a master device and a plurality of slave devices. The slave devices have a common default address in an unaddressed state and the master device and the plurality of slave devices are connected in chain via a power line and a communication line, wherein each slave device is indexed by an index greater than or equal to 1, the slave device of index 1 being connected to the master device, wherein, to address the slave device of index k, k being equal to or greater than 2, the method first instructs the slave device of index k?1 to activate the power supply of the slave device of index k via the power line, and then, it sends, to the common default address on the communication line, a command to change the common default address of the slave device of index k to a unique address of index k. Therefore, at each iteration, there is only one unaddressed slave device in the network.
