About Sensinode
Vision
•The Internet of Things (IoT) is the next evolution of the Internet where devices of all
types and capabilities are Internet accessible. IP-based Web Services will be the driving
force behind the global growth and demand for the IoT.
Mission
•To be the leading provider of software solutions to enable the Internet of Things rapidly
and cost-effectively
Heritage
• Leading supplier of end-to-end IoT software solutions since 2006
• Led the creation of 6LoWPAN and CoAP
• Key contributor to IETF, ZigBee, ETSI standardization efforts
• Company founders wrote first drafts on IP/Web over low power RF in 2002
• Founding member of IPSO (IP for Smart Objects) Alliance
6LoWPAN / CoRE

Mega-trends in IoT for Smart Cities
• Developed Cities = Retrofit
 e.g. lighting and meter upgrades, better transportation
• Developing Cities = Unlimited potential
 China: 400 Million people in 15 years to cities that don’t exist
 Digital and Ecological cities, e.g. DigiEcoCity
 New innovation, services and societies
 Mobile devices as Sensors & the Smart City UI
• Secure, re-usable IoT infrastructure
• Open IoT device development, e.g. ARM mBed (mbed.org)
• Open IoT Web & Big Data
• Permissionless Innovation!

The Business Case
• Cellular + WSN: Accessible market of up to 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…)

IoT Market Challenges
•Proprietary solutions unable to scale for volume
•Technology unable to achieve targets
 very low power / cost / data throughput
•Complex application development
•Legacy solutions incapable of supporting new use
cases, features and functionality
The Sensinode Solution
•Rapid application development environment using
standard Web services
•Optimized, secure transport and management of data
in both cellular and WSN networks
•Device software + backend application platform
•“Future proof” standards-based technology
•Deployable now with existing hardware

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

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 including
 Smart Cities
 Connected Home
