A method for managing single function devices among communication devices broadcasting messages to gateways connected to a gateway manager, a single function device being only able to broadcast a message including a command. The method comprises: the gateways receiving messages sent from communication devices, each message containing an identifier of communication device, the gateways determining quality metrics for each received message, the quality metrics pertaining to the radio link between the gateway and the communication device, the gateways storing, for each received message, a property vector comprising the identifier of the communication device and the quality metrics, the gateway manager collecting the property vectors from all the gateways, the gateway manager identifying a single function device by detecting a property vector comprising an identifier of communication device that is included in a list of single function devices, the gateway manager determining a location of the identified single function device based on the quality metrics of the detected property vector, the gateway manager coupling the identified single function device with a feedback device, based on the determined location of the single function device and on a location of the feedback device, and the gateway manager sending an order to the coupled feedback device to perform a feedback signal.

Broadcasting communicating devices management

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 identifier of communication device and quality metrics, the method including: the gateways storing, for each received message sent from communication devices, a secondary vector including 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 secondary vectors that contain the same identifier of communication device and contain timestamps included in a predefined time interval, the gateway manager commanding the pairing of the communication device corresponding to the identifier of communication device of the selected secondary vector with the gateway corresponding to the identifier of a gateway of the selected secondary vector, if the selected secondary vector has better quality metrics than a given primary vector having the same identifier of communication device in the pairing database and if the selected secondary vector has an identifier of gateway different from the identifier of gateway of said given primary vector.

A method for optimizing power supply life time of an industrial sensor platform which includes a processing unit, a power supply, and transmission means. The method identifies a sensor connected to an industrial platform, verifies a functional setting of the platform, determines sensor power consumption and sensor measurement time ts, and determines transmission power consumption of the transmission means. The method further includes acquiring input parameter settings which includes expected battery life time, sensor reading interval Ts and periodic transmission interval Tw. Which is followed by calculating an optimum for power supply life time, sensor reading interval Ts, and periodic transmission interval Tw. And adjusting settings of the platform for sensor reading interval Ts and periodic transmission interval Tw according to the optimum calculated.
