NS3 simulator

Recompile the whole program

./ns3 clean
./ns3 configure
./ns3 build

Run the sample

Programs are under the scratch folder

ex: ./ns3 run myfirst

The main program is Build_Env.cc

Input parameters

input_file: The file contains planning graph
event_file: The file contains network traffic event
unexpected_event: The file contains device failure
output_folder: The folder contains output csv files
add_event: Whether add human movement data event
  0: No
  1: Yes
record_time: The network metric recording frequency
  0: 1s
  1: 10s
simulation_time: The simulation time (s) for simulator
unexpected_event: Whether add network failure event
  0: No
  1: Yes
ground: 0 is nthu, 1 is irvine
exp_number: The number of experiment

Run once

ex: ./ns3 run Build_Env -- planning_graph_nthu/0.json network_traffic_event/0_400_0.json 10_0.txt output 0 0 60 0 0 0 

Human_movement_generator.py

Input parameters

people_size: Number of people
ground: 0 is nthu, 1 is irvine 
exp_number: The number of experiment

Run

ex: python Human_movement_generator.py 100 0 0 

movement_data_trans.py

Input parameters

input_file: The file contains human movement data
planning_graph file: The file contains planning graph

Run

ex: python movement_data_trans.py movement_data_nthu/100_0.csv planning_graph_nthu/0.json  

Unexpected_event_generaotr.py

Input parameters

ground: 0 is nthu, 1 is irvine
number_to_generate: Number of affected location
exp_number: The number of experiment

Run

ex: python Unexpected_event_generator.py 0 10 0

Run whole program

1. Create planning graph in folder planning_graph

2. Generate network traffic event

First create human movement data

  python Human_movement_generator.py 100 0 0 

Second convert to network traffic event

  python movement_data_trans.py movement_data_nthu/100_0.csv planning_graph_nthu/0.json  

3. Generate network failure event

  python Unexpected_event_generator.py 0 10 0

4. Run NS3 simulator

  ./ns3 run Build_Env -- planning_graph_nthu/0.json network_traffic_event/0_1200_0.json 10_0.txt output 0 0 60 0 0 0
