In the same way, devices can be simplified into units that are capable of sensing and actuating. In other words, devices are a lot closer to the real world compared to systems. By integrating devices with the systems, the behavior and liveliness of the systems can be greatly improved. However, doing so introduces many challenges such as Device identity and metadata management Device failure Anomaly detection Security token management Processing large amounts of data Guaranteed message delivery Device specific transports and protocols

1. Talking to Devices
Importance of a comprehensive IoT Platform

2. Device?

3. Device = Sensors + Actuators + Mgt Interface

4. How a device can enhance a software system?

5. Example :
A Fleet Management System (w/o device integration)

6. A Fleet Management System

7. Let’s integrate with a device attached to vehicle..

8. Enhanced Fleet Management System
Enhancements = Live data, Increased accuracy
Sensor Data = Location,
Speed, fuel consumption,
load, direction, driver
attentiveness, etc..

9. Device Integration comes @ a cost ..

10. Device Integration - Challenges
● Financial Costs
○ Purchasing
○ Installation
○ Maintenance
○ Depreciation
● Software Platform Challenges
○ Device enrollment, Identity, metadata management
○ Failure Detection
○ Anomaly Detection
○ Fraud Detection
○ Security Token Management
○ Storing and accessing data from devices
○ Maintaining message delivery guarantees
○ Supporting device specific transports / protocols
○ Firmware/Software distribution

11. Device Integration comes @ a cost ..
Device Integration brings new opportunities..

12. Device Integration - Opportunities
● Real time dashboards
● More accurate predictions
● Immediate physical actions

13. How an IoT Platform can help device integration?

14. Challenge
Device enrollment, Identity & Metadata Management
● Device Enrollment
○ Different type of enrollment needs
■ Self enrollment
■ Pre burnt registration codes
■ BYOD
■ COPE
■ SCEP
■ Custom workflow extensions
● Device Identity Management
○ Unique identification per device vs device group identity
○ Batch generated identities for fabrication systems
○ Bridge between human identity and device identity -> ownership
○ Support for OpenID Connect

15. Challenge
Device enrollment, identity & metadata management
● Device Metadata Management
○ Maintaining metadata about every device instance
■ Make / Model
■ Software, firmware version
■ Location
■ Hardware specification (processor, memory, I/O, ports, etc)

16. Challenge
Failure Detection
● Devices are deployed remotely -> difficult to examine physically
● Detecting failures through
○ Sensor data update frequencies
○ Erroneous values
● Triggering alerts

17. Challenge
Anomaly Detection
● Maintaining reference value ranges
● Recognising abnormal values, conditions
● Triggering alerts / cross checks when anomaly detected

18. Challenge
Predictions and Learning
● Capturing device data
● Passing captured data to learning system
● Model generation and predictions for future scenarios

19. Challenge
End to end security and Token Management

20. Challenge
End to end security and Token Management
● Ability generate and validate random security tokens
● For devices, apps reading / sending command signals from / to devices
● OAuth2 tokens for IoT
● Certificate based mutual authentication type schemes between device and IoT
platform

21. Challenge
Storing and accessing (big) data

22. Challenge
Storing and accessing (big) data

23. Challenge
Maintaining end to end message delivery guarantees
● Multiple hops between device to IoT Platform
● Different types of protocols with heterogeneous message patterns
● Low computing power on devices

24. Challenge
Supporting device specific transports / protocols

25. Challenge
Firmware / Software distribution
● Repository of firmware / software running on each device
● Analysing device’s hardware / software spec
● Pushing updates
● Roaster on pushing updates
