Try LoRaSim:

or LoraWAN extension for NS-3

Good luck !

LoRaWANSim is a good one:

Conference Paper Does Bidirectional Traffic Do More Harm Than Good in LoRaWAN...

Really Thank you very much Mustafa

Hi Mustafa,

Do you have the link for downloading this simulator (LoRaWANSim) please ?

Try LoRaSim:

or LoraWAN extension for NS-3

Good luck !

Thanks Imed.

Is LoraSim support Lora PHY please ?

See our new simulator (https://github.com/kqorany/FREE), which is more comprehensive than LoRaSim, considering the downlink capability and a theoretical packet error model, etc.

See here (http://lora.tti.unipa.it/) and here (https://flora.aalto.fi/).

According to the specs, these simulators provide:

• 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
• Statistics of energy consumption in network

This framework (https://github.com/GillesC/LoRaEnergySim) is built with Python and includes retransmission, energy consumption of individual nodes, Adapative Data Rate, ...

I have used machine learning for optimizing LoRa channel selection here. This implementation also include a system level implementation of LoRaWAN basics.

Can anyone please share where to find the LoRaWANSim, the extension of LoRaSim based on Simpy?
