Internet Of Things Forecast2020 View

• 212 billion installed things

• 30 billion autonomously connected

things• Public Sector, Distribution & Services,

Manufacturing & Resources, and Consumers lead segment growth rates

• Approximately 3 million petabytes of embedded systems data (excludes streaming, surveillance-type data

• $8.9 trillion of business value

“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 Progressive Policy Institute

GSMA “Connected Life” forecast $4.5T in 2020

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

5

The real opportunity is improved business value – new revenue models, lower costs, improved client experiences, better insight to improve outcomes

IoT

?

Is there value in combining WebRTC with IoT?

7

Why is WebRTC so disruptive?

x Eliminates complexity of delivering codecs and streaming protocolsx Closely aligned with HTML 5, programmed via JavaScriptx Support for mobile platforms and web browsersx Enables real-time data communications in addition to voice and videox Strong industry support

7

It contextualizes communications!

8

IoT is the integration point for everything,

IoT

…and a rich source of programmatically consumable context!

both physical and digital…

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?

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

WebRTC signaling and IoT networking

• 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

MQTT for massively scalable signaling

MQTT vs. HTTP/REST • 93x higher

throughput• 1/10th battery• 1/8th bandwidth

Stack size comparisonSipML5: ~5 MB vs. MQTT Paho + Rtcomm: ~ 250K
