CONNECTING SERVICES IN IOT DESIGN

RELOC s.r.l.

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.

A lot of opportunities but there still are problems and challenges.

A few examples:

VISION @product 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

Internet-of-Things

COMPLEXITY @system-level / 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 & PRIVACY @system-level / 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.

Embedded Connectivity

• Embedded connectivity requires significant HW / FW modifications vs

– Accelerate development: move firmware development at the API level

– Simplify update: abstract connectivity solution

• 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

– pre-verified device-to-cloud system components
