LoRaWAN ns-3 module

CI codecov

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

Quick links:

Getting started

Prerequisites

To run simulations using this module, you first need to install ns-3. If you are on Ubuntu/Debian/Mint, you can install the minimal required packages as follows:

sudo apt install g++ python3 cmake ninja-build git ccache

Otherwise please directly refer to the prerequisites section of the ns-3 installation page.

Note: While the ccache package is not strictly required, it is highly recommended. It can significantly enhance future compilation times by saving tens of minutes, albeit with a higher disk space cost of approximately 5GB. This disk space usage can be eventually reduced through a setting.

Then, you need to:

  1. Clone the main ns-3 codebase,
  2. Clone this repository inside the src directory therein, and
  3. Checkout the current ns-3 version supported by this module.

To install this module at the latest commit, you can use the following all-in-one command:

git clone https://gitlab.com/nsnam/ns-3-dev.git && cd ns-3-dev &&
git clone https://github.com/signetlabdei/lorawan src/lorawan &&
tag=$(< src/lorawan/NS3-VERSION) && tag=${tag#release } && git checkout $tag -b $tag

Note: When switching to any previous commit, including the latest release, always make sure to also checkout ns-3 to the correct version (NS3-VERSION file at the root of this repository) supported at that point in time.

Compilation

Ns-3 adopts a development-oriented philosophy. Before you can run anything, you'll need to compile the ns-3 code. You have two options:

  1. Compile ns-3 as a whole: Make all simulation modules available by configuring and building as follows (ensure you are in the ns-3-dev folder!):

    ./ns3 configure --enable-tests --enable-examples &&
./ns3 build

  2. Focus exclusively on the lorawan module: To expedite the compilation process, as it can take more than 30/40 minutes on slow hardware, change the configuration as follows:

    ./ns3 clean &&
./ns3 configure --enable-tests --enable-examples --enable-modules lorawan &&
./ns3 build

    The first line ensures you start from a clean build state.

Finally, ensure tests run smoothly with:

./test.py

If the script reports that all tests passed you are good to go.

If some 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
  • adr-example
  • aloha-throughput
  • frame-counter-update
  • lora-energy-model-example
  • parallel-reception-example

Examples can be run via the ./ns3 run example-name command (refer to ./ns3 run --help for more options).
