  • Patent number: 9060386
    Abstract: Disclosed herein is a method of selecting a relay node in a mobile ad-hoc network. The relay node selection method includes updating a neighbor node list based on messages received from one or more other nodes, and selecting a 1-hop neighbor node having a highest Multi-Point Relay (MPR) selector counter (MSC) value, from among one or more 1-hop neighbor nodes included in the updated neighbor node list, as an MPR node. Therefore, the present invention can prevent unnecessary channel competition and conflicts between nodes and improve network performance.

  • Patent number: 6127546
    Abstract: The present invention relates to a process for the preparation of an oxazoline compound which is easily chemically converted to a beta-amino-alpha-hydroxy acid or a gamma-amino-beta-hydroxy acid. The method comprises producing a compound of the following formula (4) using .alpha.-amino acid. The produced compound (4) is subjected to an intramolecular cyclization to produce an oxazoline compound of the following formula (3). The oxazoline compound (3) is oxidized at a vinyl group with RuCl.sub.3 or NaIO.sub.4 to produce an oxazoline compound of the following formula (1) which is easily chemically converted to a beta-amino-alpha-hydroxy acid. Alternatively, the oxazoline compound (3) may also be treated with 9-borabiclo[3.3.1]nonane such that a hydroxy group is introduced into the end of the vinyl group of the oxazoline compound(3). The introduced end hydroxy group is oxidized with RuCl.sub.3 or NaIO.sub.
