  • Publication number: 20140161008
    Abstract: Provided is a node probing method using an adaptive and asynchronous rendezvous protocol in an opportunistic network. The node probing method includes: selecting, by each of nodes in the opportunistic network, a prime number larger than two; using, by the node, the selected prime number to generate a wake-up pattern according to the following equation: x n = { 1 , if n ? 0 ? ( mod ? ? p ) ? ? or n ? 1 ? ( mod ? ? p + 1 ) 0 , others where Xn=1 represents a wake-up slot, Xn=0 represents a sleeping slot, and ‘mod p’ represents a modulo operation for the prime number p); and searching, by the node, for a neighbor node according to the generated wake-up pattern.

  • Patent number: 8705505
    Abstract: Provided is distributed medium access scheduling with implicit ordering (DSIO). The DISO includes the steps of: (a) when any terminal of a plurality of terminals included in a terminal group has data to transmit, promoting the terminal to a transmission data existence layer; (b) when any blue terminal of a plurality of blue terminals included in a blue terminal group has no data to transmit, degrading the blue terminal to a transmission data non-existence layer; and (c) when any red terminal of a plurality of red terminals included in a red terminal group succeeds in intruding between the blue terminals and recognizes whether or not to transmit data without a collision, promoting the red terminal to the blue terminal group.
