The Business Case
• Cellular + WSN: Accessible market of 500 X more devices
M2M players must look past just Cellular to grow
• Enable new business models
• Proprietary market >>> Global market
• Rapid time to market = faster growth & lower cost
• Truly inexpensive micro-controller & radio technologies
• Re-use standard IT and Web infrastructure
• Tap into a huge developer community (IP… Web…)
• Permissionless Innovation!

Key Standardization Activities
• IETF
IPv6 and 6LoWPAN networking
Routing algorithms (e.g. RPL)
Web of Things (REST for IoT, CoAP, Resource Directory etc.)
Security (DTLS, TLS, Cipher suites)
• OMA / IPSO Alliance
OMA Lightweight M2M Enabler Standard (CoAP)
IPSO Web Objects
• OneM2M
Ongoing work on M2M system standardization (CoAP, HTTP binding)
• ZigBee & WiSun
ZigBee IP - An open-standard 6LoWPAN stack for Home Area Networks
ZigBee IP NAN – 6LoWPAN stack for Sub-GHz large area applications
WiSun - Sub-GHz 802.15.4g/e and 6LoWPAN consortium

CoAP: The Web of Things Protocol
• Compact 4-byte Header
• UDP, SMS, (TCP)
• DTLS Security
• Subscription
• Discovery

IPSO Web Objects
• We need semantics to build a Web of Things
• IPSO defines Web Object guidelines (join us!)
• IPSO Application Framework published in 2012
• New IPSO Web Objects will be published soon!
Compatible with OMA Lightweight, CoAP and HTTP
General purpose IO
General sensors, Temperature, Light, Humidity, Actuators
Light control, Power control, Set Points
• Great roadmap of Objects for the future, e.g.
Smart Cities
Connected Home
