- MQTT is a publish-subscribe messaging protocol that is well-suited for IoT and mobile applications due to its lightweight design, low bandwidth usage, and high reliability over unstable network connections. It provides an alternative to HTTP for applications like connected cars that require fast, real-time communication of sensor data between devices. - Connected cars produce large amounts of sensor data but typical car network architectures are slow and unreliable for transmitting data to the cloud. MQTT can help address this by providing faster, more efficient communication compared to HTTP. - Major technology companies like IBM, Facebook, and car manufacturers are adopting MQTT for applications like predictive maintenance, autonomous driving features, and telematics that require fast, reliable transmission

2. CONNECTED CAR IS A BIG DATA PROBLEM
• car sensors produce 2GB every 90 min
• 60M cars manufactured each year
• If driven 4 hours a day ..
103 exabytes

3. HTTP IS NOT HOW YOU DO THAT
•
•
•
•
•
•
No QoS, no reliable messaging
Heavy, hundreds of bytes of overhead
Not designed for wireless, high latency
No pub/sub 1:many, many:many, etc
No, always connected, instant response
in summary, for connected car HTTP is ..
slow, heavy, unreliable

4. MQTT FOR MOBILE MESSAGING
Faster M2M and User Experience
" pub/sub with QoS - engineered for wireless
" socket, TLS 1.2, mutual authentication, etc.
" MQTT vs HTTPS on Android & 3G
– 93x faster throughput,13k msg/sec on my iPad
– 1/8th network overhead – faster, cheaper
– 1/170th battery to receive, 1/11th to send
" Open standard, open source, very fast & reliable
" eclipse.org/paho C, Java, JavaScript
" mqtt.org for dozens of languages, platforms

5. WHO’S IN THE MIX WITH MQTT?
" usual suspects: IBM, SAP, Intel, Cisco, Software
AG, TIBCO, VMWare, Red Hat, Pivotal, NIST,
Eclipse, Apache, Emerson, Axway, et al.
(even Oracle - google “JavaOne MQTT”)
" cool kids: M2Mi, 2lemetry, ThingWorx, Libelium,
Sierra Wireless, Telit, QNX, Wind River, Shaspa,
Eurotech, Elecsys, Xively, et al.
" car guys: 1/2 dozen automakers, trucks, several
tier-1 suppliers, telematics providers, etc.

7. FACEBOOK MESSENGER
“.. performance improvements designed to make your
messaging experience even better. To do this without
killing battery life, we used a protocol called MQTT …
designed to use bandwidth and batteries sparingly…
phone-to-phone in hundreds of milliseconds, rather than
multiple seconds.”

terrible response times the norm
Most are 15-90 seconds, Tesla is 5-6 sec
lack “always connected” instant response
slow, unreliable, high mobile data costs

12. IBM MESSAGESIGHT SPEEDS THE IOT
Faster IoT & Mobile user experience
MQTT, HTML5 WebSocket, JMS, MQ
+ Mobile
+ Secure
+ Easy
+ Open – MQTT, WebSocket, JMS
+ Speed – 80µs, millions/second
+ Scale – millions of things

13. PREDICTIVE MAINTENANCE
Improving owner experience
• real-time using sensor data, time-series
• proactive service, i.e. brake issue
• driving better customer service

14. BIG DATA DRIVES AUTONOMOUS
