LoRaWAN ns-3 module

Gitter chat Build Status

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

API documentation.

Module Documentation.

Getting started


To run simulations using this module, you will need to install ns-3, and clone this repository inside the src directory:

git clone ns-3
git clone ns-3/src/lorawan

If you are interested in having the latest features (and more bug-prone code), you can check out the develop branch:

cd ns-3/src/lorawan
git checkout develop


If you are interested in only compiling the lorawan module and its dependencies, copy the .ns3rc file from ns-3/utils to ns-3, where ns-3 is your ns-3 installation folder, 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 folder, configure and then build ns-3:

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

Finally, make sure tests run smoothly with:

./ -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.

Usage examples

The module includes the following examples:

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

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