ns2-simulation's Introduction

Network Models simulation using NS-2 Simulator

  1. Files present:

    • TCL Files (for modeling)
    • Awk scripts (for post-processing)
    • Shell scripts (for scripting)
    • Modified .cpp files
  2. Simulation Modes:

    • Wireless 802.11 static network
    • Wireless 802.15.4 mobile network
    • Cross-network simulations between wired and static wireless mode
    • Satellite mode
    • LTE network mode
  3. Parameters varied:

    1. For basic modes (802.11 and 802.15.4):

      Parameter Values (varied)
      No. of nodes 20, 40, 60, 80, 100
      Flow 10, 20, 30, 40, 50
      Packet rate 100, 200, 300, 400, 500
      Coverage area (only for 802.11 static) {1, 2, 3, 4, 5}.TX-Range
      Speed of nodes (only for 802.15.4 mobile) {5, 10, 15, 20, 25} m/s
    2. For additional modes, these parameters were varied

      Satellite LTE
      Orbital inclination Average Page Size
      Polar AMR
      Link Bandwidth Subscribers
  4. Metrics considered for measurement:

    • Network Throughput (Average and Instantaneous and Per-Node)
    • End-to-end Delay
    • Packet delivery and drop ratios
    • Energy consumption
    • Residual Energy per node
    • Link-Queue variation
  5. Experimented with modified simulation scenarios:

    • Congestion control mechanism
    • Queue size variation (random drop instead of drop-tail)
    • Modified RTT calculation mechanism
    • Modified MAC-Layer protocol
