WHY FOG COMPUTING ?
Increase in number of connected devices has lead to
• Need to handle exponential data
• Decision making at the Edge
• To resolve network congestion challenge

WHAT IS FOG COMPUTING ?
The fog extends the cloud to be closer to the things
that produce and act on IoT data. These devices,
called fog nodes

NETWORK

■ Faster Data Streaming
– Live Feed from Sports/News/Events
– Peer to Peer Live Feed
■ Data Factoring & Filtering
– Small Data Analytics
– Video/Image Recognition andVoice Recognition at Node and sending only
the relevant data to the cloud
– Filtering the data from the Fog Node itself
