I found an article here :(Link to the article) entitled "LoraWAN and IOTA: Proof of Concept of storing data in real time in the Tangle".

The thing is not clear to me is that if IOTA has been installed on a small device supports LoraWAN (https://lora-alliance.org/about-lorawan) in this proof of concept? (You can see an example of this small device here: Link to the device.)

And if so, which version of IOTA (which language?) this version? : https://github.com/iotaledger/iota.js ?

And if so, does it mean that it is possible to install a JavaScript version of IOTA on a small device supports LoraWAN? Because usually we need to run a C/C++ code on a device such as small devices support LoraWAN and apparently there is no version of IOTA implemented in C language in its official Github repository (https://github.com/iotaledger).

Or maybe in this proof of concept, IOTA has been installed in another more powerful device (which device? it is not clear to me.)

Am I right? What is my mistake?

Thanks

  • It might be best to ask directly the author of the article. I don't think it gives sufficient information for anyone to be able to repeat or fully understand the setup.

  • My general question is that if it is possible to install IOTA on a LoraWAN device? or as @ben75 says, the IOTA is installed on an ordinary computer? And in this case, what is the role of LoraWAN device? Thanks

LoraWAN is a protocol for data-transfer (not a device). It's a very low level protocol, specially designed for low power devices.

AFAIK, LoraWAN is designed in such a way that a small device can send messages to a nearby LoraWAN-Gateway through radio signal. The gateway have an antenna to receive messages and a high bandwidth internet connection (wifi, cellular, ...) to forward messages to the internet.

In the linked article, the strategy was to implement the iota part on a normal computer simply listening for messages on LoraWAN network and encapsulate them in an iota transaction. The author was connected to "TheThingsNetwork" : an open network of LoraWAN-Gateway.

  • Thank you. But it the article, it's mentioned they use a programmable LoraWAN based device link. So, if we've to install IOTA on a normal computer, what is role of this small device? Does it mean we've to connect this small device to a normal computer? (Otherwise, this small device is not able to run IOTA and send transaction to IOTA tangle?) How can we imagine a general view of this architecture? Thank you again

  • I think the proposed idea in the article has an architecture like this figure: imgur.com/a/ZvkgkBu Am I wrong? Thanks
