Types of application

1. High mobility High throughout: Vehicle management, connected personal devices
2. Low mobility High throughout: traffic video capturers
3. High mobility Low throughput: Battlefield communication, telemedicine, digital signage
4. Low mobility Low throughput: industrial pumps, environment, homes

Towards industry 4.0

1. Industry 1.0: Steam power, mechanisation, weaving loom
2. Industry 2.0: Assembly lines, mass production
3. Industry 3.0: Computers, Automation and electronics
4. Industry 4.0: Internet of Things, Cyber physical systems

OT Vs IT

operational technology focuses on control and management of operational devices, usually crucial in industrial context.
Here, availability is the main priority. Followed by integrity and security. Whereas in information technology security is critical, more important than integrity or availability.

the motivation behind architectures

We have a few challenges in this field

Scalability

Ipv4 is no longer enough, a shift to ipv6

Huge amount of created data

We need analytics to take place across the whole ecosystem

Security

Each node could be vulnerable

Hardware limitations

We need to leverage new designs or modify our layers

Interoperability

There are many protocols, which complicates their integration and communication

Two suggested architectures

Onem2m and IoTWF

onem2m

The idea is to create a service layer which has rest API support

IoTWF

This is more of an standardization for IoT layers.
We have seven layers
It basically divides Platform part of the hierarchy into these layers

Things later:

• Devices and sensors

Network layer

• Connectivity layer

Platform layer:

• Edge computing
• Data accumulation
• Data abstraction

Application layer:

• application
• collaboration and processes
