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
