1 CONNECTING SERVICES IN IOT DESIGN RELOC s.r.l. Conference Lake Garda, 7-8 April 2016

2 Internet-of-Things Evolution of the Internet in which everyday physical objects are seamlessly integrated into the information network, and data coming from things is mixed with information generated by people, processes and systems in order to build enhanced cooperative services and applications: it s about adding value and solving problems. 1 Things with embedded sensors and communication COLLECT ACT COMMUNICATE 2 3 ANALYZE Local and wide area networks Collect, mix, and process data

6 Internet-of-Things A lot of opportunities but there still are problems and challenges. A few examples: design IoT is about adding values and solving problems while in 2015 [IoT] progress was documented by the number of devices that were connected online [ ]. This is like measuring a hospital by the number of patients rather than how effective it is at curing people. Focus on the analysis phase (problem identification, solution analysis, user experience,..) and product differentiation Efficient implementation based on design reuse platform-based design

7 Internet-of-Things / embedded Internet-of-Things applications include critical design parts, e.g. communication (numerous protocols both at transport and application layer), cloud-service (multitude of solutions available) calling for specific design competences. Pre-verified ready-to-use platform components (reduce risk, accelerate design, simplify update and protocol migration) SECURITY & / embedded Potential security vulnerabilities involving encryption, permissions, password security. Products vulnerabilities stress unlawful surveillance / privacy issues. Device with encryption capabilities for secure end-to-end communications; Robust secured remote update procedures to potentially fix security issues.

8 System Architecture Cloud Services User Interface Networking Smart Objects

9 Embedded Connectivity Embedded connectivity requires significant HW / FW modifications vs Accelerate development: move firmware development at the API level Simplify update: abstract connectivity solution

10 Cloud Services and Applications Challenges of interaction with cloud services Multiple device-to-cloud protocols Multiple semantics and APIs Different device management (e.g. provisioning) Test and field monitoring challenges Requires industry proven solution for fast adoption Internet-of-Things ready-to-use starter-kits comprehensive application examples CoAP pre-verified device-to-cloud system components
