Prerequisites

Custom version of NS-3 and specified version of ndnSIM needs to be installed.

The code should also work with the latest version of ndnSIM, but it is not guaranteed.

mkdir ndnSIM
cd ndnSIM

git clone -b ndnSIM-2.5 https://github.com/named-data-ndnSIM/ns-3-dev.git ns-3
git clone -b 0.18.0 https://github.com/named-data-ndnSIM/pybindgen.git pybindgen
git clone -b ndnSIM-2.5 --recursive https://github.com/named-data-ndnSIM/ndnSIM ns-3/src/ndnSIM

# Build and install NS-3 and ndnSIM
cd ns-3
./waf configure -d optimized
./waf
sudo ./waf install

# When using Linux, run
# sudo ldconfig

# When using Freebsd, run
# sudo ldconfig -a

cd ..
git clone https://github.com/named-data-ndnSIM/scenario-template.git my-simulations
cd my-simulations

./waf configure
./waf --run scenario

After which you can proceed to compile and run the code

For more information how to install NS-3 and ndnSIM, please refer to http://ndnsim.net website.

Compiling

To configure in optimized mode without logging (default):

./waf configure

To configure in optimized mode with scenario logging enabled (logging in NS-3 and ndnSIM modules will still be disabled, but you can see output from NS_LOG* calls from your scenarios and extensions):

./waf configure --logging

To configure in debug mode with all logging enabled

./waf configure --debug

If you have installed NS-3 in a non-standard location, you may need to set up PKG_CONFIG_PATH variable.

Running

Normally, you can run scenarios either directly

./build/<scenario_name>

or using waf

./waf --run <scenario_name>

If NS-3 is installed in a non-standard location, on some platforms (e.g., Linux) you need to specify LD_LIBRARY_PATH variable:

LD_LIBRARY_PATH=/usr/local/lib ./build/<scenario_name>

or

LD_LIBRARY_PATH=/usr/local/lib ./waf --run <scenario_name>

To run scenario using debugger, use the following command:

gdb --args ./build/<scenario_name>

Running with visualizer

There are several tricks to run scenarios in visualizer. Before you can do it, you need to set up environment variables for python to find visualizer module. The easiest way to do it using the following commands:

cd ns-dev/ns-3
./waf shell

After these command, you will have complete environment to run the vizualizer.

The following will run scenario with visualizer:

./waf --run <scenario_name> --vis

or

PKG_LIBRARY_PATH=/usr/local/lib ./waf --run <scenario_name> --vis

If you want to request automatic node placement, set up additional environment variable:

NS_VIS_ASSIGN=1 ./waf --run <scenario_name> --vis

or

PKG_LIBRARY_PATH=/usr/local/lib NS_VIS_ASSIGN=1 ./waf --run <scenario_name> --vis
