2. HTTP IS NOT THE IOT’S FRIEND
•
•
•
•
•
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
in summary, for connected car HTTP is ..
Slow, heavy, unreliable
3. MQTT FOR MOBILE MESSAGING
Faster M2M and User Experience
" pub/sub with QoS - engineered for wireless
" socket, TLS 1.2, mutual auth, 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
4. WHO’S IN THE MIX?
" 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, et al.
" car guys: 1/2 dozen automakers, several tier-1
suppliers, telematics, car remotes, etc.
5. FACEBOOK MESSENGER
" 725M mobile users, popular, highly rated, very fast
" Speed of UX is big competitive advantage

6. 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.”
- Lucy Zhang, Facebook Engineer

7. TRY IT FOR YOURSELF
Facebook Messenger
MQTT
vs
Google Hangouts
MQTT
8. TRY IT FOR YOURSELF
Most 1 star complaints are about
slowness and presence services
(who’s online) not working correctly
Google Hangouts
MQTT
9. THE CAR IS A MOBILE “THING”
needing less driver distraction, better safety
“Latency is a driver distraction issue”
– Roger Lanctot @rogermud

terrible response times the norm
Most are 30-90 seconds, best case 15 sec
lacks “always connected” instant response
slow, unreliable, high mobile data costs

11. CONNECTED CAR REINVENTED
" 20x faster UX
Insurer
" 5x faster dev
" 10x cheaper

12. IBM MESSAGESIGHT SPEEDS IOT
IoT & Mobile Messaging
for MQTT, HTML5 WebSocket, JMS, MQ
+ Mobile
+ Secure
+ Easy
+ Open – MQTT, WebSocket, JMS
+ Speed – 80µs, millions/second
+ Scale – millions of things
13. CONNECTED CAR IS BIG DATA
• car sensors produce 2GB every 90 min
• 60M cars manufactured each year
• If driven 4 hours a day ..
103 exabytes
14. PREDICTIVE MAINTENANCE
Improving owner experience
• real-time using sensor data, time-series
• proactive service, i.e. brake issue
• driving better customer service
15. BIG DATA DRIVES AUTONOMOUS
car2cloud2car improves driver safety & experience
assisted & autonomous driving with real-time big data
autonomous isn’t just about “my car”

16. WHO IS DOING WHAT IN CARS
.. that I can talk about publicly
Connected Car & M2M Provider
" mobile2cloud2car w “key fob response time”
" demo: youtu.be/V1ooTX4aTE8
" Press: NYT, WSJ, Fortune, etc.
2nd largest OE supplier
" CEO announce Sept 10 Frankfurt Motor Show
" IBM Car Cloud for “autonomous driving”
" Press: NYT, Bloomberg, CNET, Reuters, etc.
" Look for me in Conti’s CES `14 booth
(also QNX’s, IBM’s)
21. “MQTT FOR SENSOR NETWORKS”
MQTT-SN speeds your WSNs
• MQTT for WSNs
• datagram instead of socket
– even smaller footprint
– very low power
– very low bandwidth
– QoS reliable messaging in unreliable conditions
• ZigBee, 6LoWPAN, DSRC, UDP, serial, et al.
• bit.ly/mqttsn specification
22. ECLIPSE MOSQUITTO W MQTT-SN
• Nov 19 – Eclipse Mosquitto project live
“RSMB” source now in github
• 74KB for embedded systems
• MQTT + MQTT-SN server & bridge
• Bridges WSNs to Cloud
• Used in “things” ranging from US & UK military
sensor fabric to home automation
• bit.ly/mqtt-sn for source, also google “RSMB”
