•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…)

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
