  • Patent number: 10172021
    Abstract: A first node included in a first layer determines whether there has occurred a failure in a sink node included in a second layer subordinate to the first layer. The first node requests a second node included in the second layer to collect information of a third node included in a third layer subordinate to the second layer when the first node determines that there has occurred a failure in the sink node. The first node determines a fourth node serving as a substitute for the failed sink node included in the second layer on a basis of the information of the third node collected by the second node.

  • Patent number: 10091095
    Abstract: A system has a group of nodes that perform multi-hop communication therebetween and a communications apparatus that communicates with a node included in the group of nodes. The node adds to data transmitted by the node, a hop count updated each time the data is transferred by the multi-hop communication and a reference hop count for the data to be transferred from the node to the communications apparatus, and transmits the data. The communications apparatus, when receiving the data, compares the reference hop count and the hop count added to the data, and based on a result of comparison, determines whether failure has occurred at a given node in the group of nodes.

  • Patent number: 9955402
    Abstract: When a first sensor node has a large power consumption, an information processing apparatus propagates a portion of request information for a data process having the request recipient set to a second sensor node, through a path that does not pass through the first sensor node. For example, the information processing apparatus changes a division rate at a third sensor node acting as a branching point for the request information for the data process having the request recipient set to the second sensor node to thereby change the distribution of the transferred data amount and equalize the power consumption of the sensor nodes in a sensor network.

  • Patent number: 9929898
    Abstract: A sensor node among sensor nodes that synchronously switch between a first state and a second state transmits an abnormality notification signal to a collecting apparatus when in the first state and an abnormality occurs at the sensor node. The sensor node, when in the second state, transmits to the communications apparatus, a data signal that differs from the abnormality notification signal. During each interval of the first state, the sensor node enters a third state during a first partial interval of the interval of the first state, and receives and transfers an abnormality notification signal transmitted by another sensor node among the sensor nodes. During each interval of the first state, the sensor node further enters a fourth state during a second partial interval of the interval of the first state and different from the first partial interval, and refrains from receiving the abnormality notification signal.
