  • Patent number: 10078607
    Abstract: The present disclosure provides a method for managing buffers of a device for Universal Serial Bus (USB) communication in a wireless environment. The method includes determining respective current data storage levels of transmit buffers that store different types of data for USB communication; comparing the respective current data storage levels of the transmit buffers with corresponding respective predetermined threshold levels; and controlling an input rate or output rate of a first transmit buffer if it is determined based on the comparison that the first transmit buffer has a current data storage level that exceeds a predetermined threshold level.

  • Patent number: 9749815
    Abstract: In a method for communicating among a plurality of nodes in a content-centric networking environment, each of a plurality of nodes selects at least one relay node based on topology information on neighbor nodes adjacent within 2 hops from itself. Each of the selected relay nodes determines whether itself is a publisher relay node. Each of the determined publisher relay nodes generates a multi-hop content announce (CA) message including content information of its own 1-hop neighbor nodes, and broadcasts the multi-hop CA message to the plurality of nodes through the selected relay nodes.
