3. INTRODUCTION
 Fog computing is a horizontal, system-level architecture that
distributes computing, storage, control and networking
functions closer to the users along a cloud-to-thing
continuum[1].
 It has three essential attributes[1]:
 Horizontal Architecture
 Cloud-to-things Continuum
 System-level

4. Why we need fog?
 According to Cisco report
Total volume of data generated b IoT will reach 600 ZB per
year by , which is 275 times higher than projected traffic
going from data centers to end users/devices, 39 times higher
than total projected data center traffic[2].
 Problem with cloud[1]
High latency
Cost
Security

6. OpenFog Consortium
 OpenFog Consortium aimed at the standardization and promotion
of fog computing in various capacities and fields.
 The goal is to create an open reference architecture for fog
computing, build operational models and testbeds, define and
advance technology, educate the market.
 OpenFog released its reference architecture for fog computing on
13 February 2017.[5]
 In July 2018, the IEEE Standards Assocation announced it had
adopted the OpenFog Reference Architecture as the first standard
for fog computing.[6]

9.  OpenFog RA is a composite of perspectives and multiple stakeholder
views used to satisfy a given fog computing deployment or scenario[4].
 The three views that include Software, System, and Node.
 Software view :- is represented in the top three layers shown in the
architecture description, and include Application Services, Application
Support, and Node Management (IB) and Software Backplane.
 System view :- is represented in the middle layers shown in the
architecture description, which include Hardware Virtualization down
through the Hardware Platform Infrastructure.
 Node view :- is represented in the bottom two layers , which includes
the Protocol Abstraction Layer and Sensors, Actuators, and Control

10. Use Cases
Transportation Scenario: smart Cars and Traffic
control
Smart Buildings
Video Surveillance

11. Cloud Computing Fog Computing
High latency Low latency
No user-defined security User-defined security
Prone to attack Safe from attack
No location awareness Location awareness

12. Advantages
Real-time processing
Privacy
Cost
