This is an ns-3 module that can be used to perform simulations of a LoRaWAN network.

To run simulations using this module, you will need to install ns-3, and clone this repository inside the src directory. Required dependencies include mercurial and a build environment.

On Ubuntu, run the following to install all the required packets:

sudo apt install git mercurial build-essential

On macOS, you can install the command line tools with:

xcode-select --install

while Mercurial and git can be installed via Homebrew:

brew install mercurial git

Assuming you have mercurial installed, the procedure to get both ns-3 and the lorawan module is the following:

hg clone http://code.nsnam.org/ns-3-dev
cd ns-3-dev/src
git clone git@github.com:DvdMgr/lorawan

If you are interested in only compiling the lorawan module and its dependencies, copy the .ns3rc file from ns-3-dev/utils to ns-3-dev, and only enable the desired module by making sure the file contains the following line:

modules_enabled = ['lorawan']

To compile, move to the ns-3-dev folder, configure and then build ns-3:

./waf configure --enable-tests --enable-examples
./waf build

Finally, make sure tests run smoothly with:

./test.py -s lorawan

If the script returns that the lorawan test suite passed, you are good to go. Otherwise, if tests fail or crash, consider filing an issue.

The module includes the following examples:

• simple-lorawan-network-example
• complete-lorawan-network-example
• network-server-example

Examples can be run via the ./waf --run example-name command.
