Hi, I search for existant simulators for a LoRaWAN network. Have you any idea about this. i found the simpY and the LoRaSIM. I don’t know if there are other tools for a LoRaWAN simulation.Thanks ---

I not understand what parts of LORAWAN you want to emulate. As for me - i need device emulation. so i take lora\_gateway software (lora\_net), remove spi connection to hardware SX1301 and add device packets generation. So i can simulate device transmissions to network server (TTN) and can test my application server. ---

SimPy is a process-based discrete-event simulation framework based on standard Python. LoRaSIM is written using simpY. Apart from lorasim their is LoRaWANSim, a simulator which extends the LoRaSim tool to add support for the LoRaWAN MAC protocol, which employs bidirectional communication. you can check this: > **[Does Bidirectional Traffic Do More Harm Than Good in LoRaWAN Based LPWA...](https://www.researchgate.net/publication/316089079_Does_Bidirectional_Traffic_Do_More_Harm_Than_Good_in_LoRaWAN_Based_LPWA_Networks)** > > Request PDF on ResearchGate | Does Bidirectional Traffic Do More Harm Than Good in LoRaWAN Based LPWA Networks? | The need for low power, long range and low cost connectivity to meet the requirements of IoT applications has led to the emergence of... ---

> [@prashant](#): > > LoRaWANSim I had already read this paper, few months ago, it’s quite interesting though. But, I am much more interested on the tools than the results they got. Do you know if the authors put this tool available for other researchers? Thanks. ---

do you realize this topic is more then a year OLD … 🤨 ---

Well… actually yes. I still believe that someone can give me important information. Am I wrong? ---

you reacted to a user… _and that user haven’t been seen in over a year._ So don’t expect an answer with 'important information soon 😉 ---

I didn’t realized that this specific user haven’t been seen in for more than 1 year. 😐 Anyway, I’m not looking for this specific user’s answer but for anyone from the community. Actually I would like to know if anyone had already used this tool, or any other LoRaWAN simulation tool. Thanks, @BoRRoZ! ---

Nice, @BoRRoZ. This is actually the paper referenced at this very topic, 1 year ago. I believe that I reached this topic, after reading the paper and searching for references. It’s interesting, they show some nice results, but they don’t say much about the simulation tool. Do you know if it’s possible to have access to this tool? Thanks again. ---

sorry No idea… maybe you could sent a mail to the mentioned address … 🤔 ---
