FLoRa – Framework for LoRa

FLoRa (Framework for LoRa) is a simulation framework developed by Mariusz Slabicki, Gopika Premsankar for carrying out end-to-end simulations for LoRa networks. It is based on the OMNeT++ network simulator and uses components from the INET framework as well[1].

Features of FLpRa[3]

FLoRa allows the creation of LoRa networks with modules for LoRa nodes, gateway(s) and a network server.
Application logic can be deployed as independent modules that are connected with the network server.
The network server and nodes support dynamic management of configuration parameters through Adaptive Data Rate (ADR).
Accurate model of LoRa physical layer (including collisions and capture effect)
Simulations with one (or more) gateways in the network
End-to-end simulations, including accurate modeling of the backhaul network
The energy consumption statistics are collected in every node.

The article[4] provides the overviews and the design of FLoRa and some of its key features.

The following diagram from[4] describes the Modules available in FLoRa and the corresponding protocol stack.

Using Suitable FLoRa Version

FLoRA was initially released in 2017 and has received several updates since then. We may check the old versions and their compatibility with the different OMNeT++ version and INET versions at [3].

In this article, we will use the FLoRa version 1.1.0 that was released on June 9, 2022. This version has the updated code for OMNeT++ 6 and INET 4.4. So we have to install OMNeT++ 6 and INET 4.4 to use this version of FLoRa.
