  • Patent number: 10608875
    Abstract: A method is developed for dynamically configuring a network with numerous subnets, each subnet comprising at least one router node and said network comprising at least one subnet server. For enhancing the efficiency, the determination of a subnet master for configuring a subnet is carried out with two parallel processes: election of a subnet master among the router nodes of said subnet allocation to each router node of said subnet of a subnet identifier. Configuration of the subnet, achieved by the subnet master with its allocated subnet identifier, is refreshed regularly, in particular when detecting a change in the configuration of the network.

  • Patent number: 9992295
    Abstract: A communication method is provided in a communication network, including a plurality of devices forming an ordered communication segment. At least one intermediate device of this segment is connected to at most two other devices called a previous device and a next device. The intermediate device receives data from the previous device and emits at least these data to the next device to propagate the data on the segment. A concentrator initializes transmission of a first frame of data through the segment to a terminal device ending the segment, which sends back a symbol initiating transmission of a second frame of data to the first concentrator through the segment. The method includes receiving a first symbol from the previous device, which triggers emitting a WAIT symbol to the previous device and emitting at least first symbol to the next device.

  • Patent number: 8520587
    Abstract: The invention relates to a device, a method and an apparatus for acquiring data, the device comprising a wireless network including a set of nodes (100), each node (100) including a sender (140) and a receiver (150) for sending and/or receiving and/or relaying data and/or commands, and a satellite positioning system (130), characterized in that each satellite positioning system (130) includes means for providing specific data used for time-stamping the data relative to a common time reference, organizing an access to the wireless network in a perfectly controlled manner, and routing data and/or commands within the network.

  • Patent number: 7869443
    Abstract: The invention relates to a device and a method, data acquisition device consisting of a wireless network comprising a first assembly of nodes, termed active nodes (100) of the network, and a second assembly of nodes, termed peripheral nodes (110) of the network, network for which one wishes to perform an access from peripheral nodes (110) to the network of active nodes (100), characterized in that it comprises means for organizing in a perfectly controlled manner a routing of the data and/or commands within the network of active nodes (100) according to a first mode of transmission of data and/or of commands, and means for transmitting data between the peripheral nodes (110) and the active nodes (100) according to a second mode of transmission of data, said first mode of transmission of data and/or of commands and said second mode of transmission of data being temporally separated.
