" ... and increase goodput."
Isn't 'goodput' what you get when you've increased throughput?
"... an increased delay.", "... a moderate packet payload size ..."
I can't imagine that my fridge or central heating controller would be bothered or affected by an inreased delay or have anything more than a small packet payload size. Is this about the IoT things or the neighbourhood network data gathering process?
Alternatively, I can imagine the problems involved in controlling individual IoT enabled lightbulbs and kettles in a large office building; if you want to go down that route.
