While this sounds good at first, I think the idea would work best at
peace time. Please consider:

 - the majority of IoT is located in cities, so large area of the
   country has very poor coverage

 - the power blackout will render huge area of country into a sensory
   fog

 - it is possible to inject false positives into this system

So I suppose mil will stick to something that actually works and can
use diesel generator, is already integrated into air defences etc.
