LoRaSIM Simulator

LoRaSIM Simulator

This package provides a simulator of the LoRaWAN 1.1 protocol and a simulator of the LoRaWAN protocol using the PoI-based blockchain for identification.

This simulator generates a LoRaWAN topology where end devices can join the network by performing a join procedure.

Overview

The PoI-based blockchain LoRaWAN architecture aims to process the join procedure in the network servers instead of the join servers. For this, the join servers send their data (DevEUI associated to end devices authorized to connect the network) to the network servers wich create blocks to compose the blockchain.

Implementation

To implement the LoRaWAN simulator we have provided an object-oriented implementation in python.

The blockchain can be fin in the Block4PoId repository.

Paper

The paper has been accepted at ISNCC'23 and selected Best paper award.

Usage

First install the requirements: pip install -r ./requirements/requirements.txt

To run the version with/without the blockchain (from the folder src): python ./main_{with;without}_blockchain.py

N.B.: If you want to modify the positioning strategy or else, you have to modify the associated function in the right file. Like generate_Strat_Gateway in the file utils/Gateway.py.
