The document discusses the growth of the Internet of Things (IoT) and smart cities. It notes that as more devices become internet-connected, standards like IPv6, 6LoWPAN, and CoAP will be important to enable interoperability. The Web of Things uses these standards and protocols like CoAP to provide web services at the network edge for IoT applications. Sensinode is a provider of end-to-end IoT software solutions and plays a key role in several IoT standardization efforts.

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…)
