The IoT protocol obviously, that is the idea of.

And that defeats the idea of IoT which presumes a flat network of
things. One cannot have both, a layered infrastructure of application
protocols (dependency on the area, not to be confused with OSI layers)
and an internet of things.
I don't argue for or against either, I only make an observation that OPC
and MQTT do not fit into the latter architecture.
