We would call it Flake Computing, as opposed to Cloud Computing.
Think of it like Cloud Computing without Internet...
For example, you are on your boat, crossing an ocean, you do not pay those big fees to get a satellite communication and connexion, but your boat is equipped with sensors - TCP (or so) enabled. You have a single board computer on board (<- now THAT's a good one! like a Raspberry Pi, BeagleBone, etc), that can emit its own network.
Nothing is preventing you from pulling the data emitted by the sensors, to process and compute them. Networks and Internet are different things... LAN, WAN, etc. (EZ: Entropy Zero...)
