Using fog computing

Fog computing, fog networking, or fogging is a computation paradigm where the cloud comes closer to the earth or the fog layer. This layer has the computational infrastructure needed to run most essential operations and has all the features that a typical cloud would have but runs locally.

The primary difference between cloud computing and fog computing is that the sensor/actuator network does not heavily rely on the internet to work.

Take a look at this IoT stack built using fog computing:

In the stack, the sensor nodes do not directly talk to the gateway. Instead, they talk to an Edge Router, which is responsible for ...
