Basic Science & Engineering

  • E.g. Mobility affects network model/protocol
  • Time-space view vs. space view
  • View consistency in asynchronous systems
    • Wu & Dai (IEEE Network’05): function of multiple views
  • Evolving graph model: connectivity & routing
    • Ferreira (IEEE Network’04), two papers in CHANTS’07
    • Managing complexity: reduction from time-space to space
