  • Patent number: 10552458
    Abstract: A data transmission device that transmits data to another node, the data transmission device including: data storing unit for storing data; summary information storing unit for classifying data stored in the data storing unit into prescribed groups and for storing summary information that represents the number of pieces of data for each group; receiving unit for receiving summary information from the other node; selecting unit for selecting data to be transmitted based on the summary information received from the other node; and transmitting unit for transmitting the data selected by the selecting unit. The selecting unit favorably preferentially selects data included in a group with a smaller number of pieces of data based on the summary information received from the other node. Due to such a configuration, information with a high possibility of not being possessed by a communication partner can be selected and transmitted in a data sharing system.

  • Publication number: 20190306050
    Abstract: A radio communication system in which a master node collects data acquired by a plurality of sensor nodes. The master node transmits, to the plurality of sensor nodes, a data transmission request including held data information that is information related to data already held by the master node. The sensor node transmits, to the master node, data not held by the master node on the basis of the held data information, and transfers the data transmission request to another sensor node.

  • Patent number: 10375568
    Abstract: In a communication method in a wireless communication system configured from a wireless connection providing apparatus (a wireless LAN access point) and a wireless communication apparatus (a wireless LAN client), the wireless connection providing apparatus acquires subscription information for specifying necessary information and includes the subscription information in a control frame notifying surroundings of presence of itself and then transmits the subscription information. The wireless communication apparatus receives the control frame, determines whether the wireless communication apparatus retains information which is specified as being necessary by the subscription information included in the control frame. When the wireless communication apparatus retains the information, the wireless communication apparatus establishes connection to the wireless connection providing apparatus and transmits the information. The subscription information can be stored in an ESSID of a beacon frame, for example.
