Does the NS 3 simulator support the LoRa and the Adaptive Data Rate feature in the LoRa?

Yes, LoRa and Adaptive Data Rate (ADR) characteristics are assisted by an NS-3 simulator with the aid of supplementary modules and libraries. Based on how NS-3 assists LoRaWAN and ADR, we offer general explanations in an explicit manner:

Assistance for LoRa in NS-3

1. NS-3 LoRaWAN Module

• The NS-3 LoRaWAN module is considered as an extension. For LoRaWAN in NS-3, it offers extensive assistance.
• Various fundamental LoRaWAN-based characteristics such as the ADR characteristic, LoRa MAC layer, and Class A devices are encompassed in this module.

Characteristics of the NS-3 LoRaWAN Module

• LoRa MAC Layer:
• On the basis of the LoRa Alliance requirements, it applies the LoRaWAN MAC layer.
• LoRa PHY Layer:
• It specifically designs data rates, spreading factors (SF), and LoRa PHY modulation.
• Adaptive Data Rate (ADR):

How to Utilize the LoRaWAN Module in NS-3?

1. Installation Process:

• Initially, copy the loRaWAN module. Within the NS-3 simulator, combine it appropriately.

# Clone the NS-3 LoRaWAN module

git clone https://github.com/iot-simulator/ns-3-lorawan.git

# Navigate to the NS-3 directory and integrate the LoRaWAN module

cd ns-3-allinone/ns-3-dev

cp -r path/to/ns-3-lorawan/lorawan.

2. Set up and Develop NS-3:

using namespace ns3;

int main (int argc, char *argv[])

    endDevices.Create (10);

    NodeContainer gateways;

    // Configure Mobility

    MobilityHelper mobility;

    mobility.SetPositionAllocator (“ns3::UniformDiscPositionAllocator”,

                                   “X”, DoubleValue (5000),

                                   “Y”, DoubleValue (5000),
