  • Patent number: 10278233
    Abstract: According to one embodiment, a communication apparatus includes a radio interface unit that sends a data message to a receiver and extracts, when a message sent by the receiver via unicast with an optimized transmission rate is received, rate information indicating the optimized transmission rate of the receiver from the received message, a message processor that generates the data message, in which a multicast identifier indicating a multicast group is a destination, and outputs the data message to the radio interface unit, and a selector that selects, according to the rate information, a data message transmission rate to send the data message.

  • Patent number: 10187818
    Abstract: According to one embodiment, a communication apparatus includes a congestion degree calculating unit and an operation mode setting unit. The congestion degree calculating unit calculates a third congestion degree related to wireless communication based on a first congestion degree of first wireless communication and a second congestion degree of second wireless communication. In the first wireless communication, peer-to-peer communication is performed directly between communication apparatuses, and in the second wireless communication, communication is performed through a wireless communication device. The operation mode setting unit switches an operation mode of the first wireless communication based on the third congestion degree to either of a mode in which the communication apparatus transmits content or a mode in which the communication apparatus receives content.

  • Publication number: 20180248611
    Abstract: According to one embodiment, a route generating device exists in a multi-hop wireless mesh network including a transmission terminal, a destination group including a destination terminal, and a first relay group including a plurality of first wireless communication terminals. The route generating device includes a circuitry and a memory. The circuitry sets one of the plurality of first wireless communication terminals included in the first relay group as a first relay terminal, based on a connectivity in respect to the destination group. Furthermore, the circuitry generates a first route information for the first relay terminal to transfer data to the destination terminal when the first relay terminal receives the data, and transmits the first route information to the first relay terminal. The memory stores the first route information.

  • Publication number: 20050079188
    Abstract: A base for a skin external composition comprises, as a main ingredient, an alkylene oxide derivative represented by the following formula (I): R1O—[(AO)m(EO)n]—R2??(I) wherein AO is an oxyalkylene group having a carbon number of 3 to 4; EO is an oxyethylene group; and R1 and R2 may be the same or different, and are a hydrocarbon group having a carbon number of 1 to 4, or a hydrogen atom. The base is a water-soluble base that can exert both of the smooth feeling and the moist feeling.
