Fog computing

Fog computing describes a scenario where a huge number of heterogeneous (wireless and sometimes autonomous) ubiquitous and decentralized devices communicate and potentially cooperate among them and with the network to perform storage and processing tasks without the intervention of third parties.

Fog computing is a geographically distributed computing architecture with a re- source pool that consists of one or more ubiquitously connected heterogeneous de- vices at the edge of network and not exclusively seamlessly backed by cloud ser- vices. This network collaboratively provides elastic computation, storage and com- munication in isolated environments to many clients within proximity.
