This is an ns-3 module that can be used to perform simulations of a LoRaWAN network. The orginal module which is intended for Class A has now been extended for LoRaWAN Class B.
Please read the README-EXTENSION.md for the extension that is added on the orginal module to include
LoRaWAN Class B multicast which can also be used for LoRaWAN Class B unicast by using multicast groups with one member.
The Class B module also impliments the "Ping-slot relaying" algorithm proposed in [4] and [5] to improve multicast performance.
Please see README-EXTENSION.md for running this this module with ns-3.29.
Currently the following steps in this subsection do not work for this version of module. For the following to work, this code need to be ported and merged to the latest version of the Class-A simulator.
To run simulations using this module, you will need to install ns-3, and clone
this repository inside the src directory:
git clone https://github.com/nsnam/ns-3-dev-git ns-3
git clone https://github.com/signetlabdei/lorawan ns-3/src/lorawanIf 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 developIf 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-dev folder, configure and then build ns-3:
./waf configure --enable-tests --enable-examples
./waf buildFinally, make sure tests run smoothly with:
./test.py -s lorawanIf 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-examplecomplete-lorawan-network-examplenetwork-server-example- See the
README-EXTENSION.mdfor Class B example.
Examples can be run via the ./waf --run example-name command.

The initial version of this code was developed as part of a master's thesis at the University of Padova, under the supervision of Prof. Lorenzo Vangelista, Prof. Michele Zorzi and with the help of Marco Centenaro.
The LoRaWAN Class B multicast part was later added as part of an master's thesis at the Technical University of Delft, under the supervision of Dr. Ir. Fernando Kuipers.
