Sal,
Thank you for forwarding this graphic.
I find this graphic intriguing, and a good straw man starting point. But I am concerned that it is misleading. In the enthusiasm to try to leverage the successful pattern of the OSI model, we are force-fitting IoT into a model that doesn't quite work.
Specifically, I have the following immediate concerns:
- IoT in this model seems to be limited to "sensors". I don't see how the Big Data layers apply to "actuators." And I don't see how the "processors" conform to any but Layers 5 and 6. Perhaps I am being narrow-minded in clinging to the notion of IoT as representing sensors, processors, and actuators (and applications?).
- I am uncomfortable with the notion that the Cloud layer is a necessary layer. Many IoT implementations are highly localized and will not require the Cloud or Big Data.
I suspect that other concerns will arise as we look at it longer.
I find that this model represents one view on one part of IoT. It may be a big and important part. But I don't think it is adequate to define all of IoT. And I fear that it will force people into thinking about IoT in only this way and lose sight of effective and efficient solutions that do not conform to this model.
