Few technologies have the potential to benefit from IoT the way WebRTC can. In many ways, these technologies are a perfect match. IoT networks built on technologies such as MQTT are a perfect signaling platform for WebRTC and are enabling new ways to connect "things" together using real-time media. In this new world almost any event can trigger the flow of media between endpoints. Whether it be a social media event triggering a broadcasted phone call or a video analytics event triggering a surveillance camera connecting to a supervisor, IoT networks are becoming the integration point for the world. This session will explore several WebRTC related IoT use cases along with open source tools that are being used in production today to integrate WebRTC with everything from analytics, to Arduino devices, to social media, and everything in between.

“The Internet of [Things] could raise the level of U.S. gross
domestic product by 2%-5% by 2025.
This gain… if realized, would boost the annual U.S. GDP growth rate by 0.2%-0.4%
points over this period, bringing growth closer to 3% per year.” – US

4. Benefits of real-time data from Internet of Things
Monetize
• Charge for usage that is tracked by things
• Enable pay-per-use models of things
Optimize
• Improve efficiency of activities with data from
things
• Anticipate & predict optimal actions and
responses
Extend
• Provide more value through connected things
• Deliver data, content, services through things
Control
• Remotely affect behavior by controlling things
• Make remote adjustments to optimize things

Is there value in combining WebRTC with IoT?

7. Why is WebRTC so disruptive?
6
x Eliminates complexity of delivering codecs and streaming protocols
x Closely aligned with HTML 5, programmed via JavaScript
x Support for mobile platforms and web browsers
x Enables real-time data communications in addition to voice and video
x Strong industry support

 It contextualizes communications!

Why is IoT so disruptive?

9. What is context relative to WebRTC?
A. Data derived from interactions with a web site?
B. Transactional data stored in a business system?
C. Information derived from streaming analytics?
D. Sensor data from an IoT device?
E. All of the above?
8
Context is being combined with WebRTC to:
• Provide whitelist for who should be communicating
• Provide triggers to initiate real-time interactions
• Provide subject matter for real-time interactions
• Provide real-time feedback on what is being communicated

16. WebRTC signaling and IoT networking
15
• To support WebRTC enabled “things”, IoT enabled signaling helps
• IoT Protocol Options
• MQ Telemetry Transport (MQTT)
• Constrained Application Protocol (CoAP)
• Data Distribution Service (DDS)
• Matrix

17. Why MQTT for WebRTC Signaling?
• Open, lightweight, secure and massively scalable
• Simple authorization through MQTT topic ACLs
• Clients available on mobile platforms and JavaScript
• Simple IoT integration
• Extensible through JMS
