Bonjour tout le monde, $who am I ?
● Philippe Coval
– Samsung Software engineer
● belongs to OpenSource Group
● member of SRUK team
– based in Rennes, France
● Interests:
– Libre Soft/Hard/ware communities
– IoT, DIY, Embedded, Automotive…
● Need help? Find me online:
– https://wiki.tizen.org/wiki/User:Pcoval

Agenda
● State of the art
– Learn lessons from success of WWW
● Some IoT challenges
– Privacy & Interoperability
● From IoT to Web of Things
● More...

“Out of clutter, find simplicity.”
~Albert Einstein

IoT status
● The Internet of Things is a system of physical objects
– that can be discovered, monitored, controlled,
– or interacted with by electronic devices
– that communicate over various networking interfaces
● and eventually can be connected to the wider Internet.
● Addresses many domains:
– Health, Agriculture, Transport, Cities, Industry
● Lot of Technical skills needed:
– Hardware: Electronic design & Power management, Security
– Software: Interoperability, OS, update, frameworks, Privacy
– Networking / Connectivity: Wired or Wireless protocols

How IoT and Web differ for developers?
Web IoT
Goal: Publish contents, link, Social... Control/monitor devices
Origin, History: IP, 1989: URL+HTML+HTTP 1982: “Coke” M2M, 1999: IoT
2015 (>mobiles), 2017+30%
Architecture Client/Server mostly C/S, Mesh, D2D, Wireless
Open Standards RFCs,IETF, IRTF, ISOC, IAB,
W3C, ECMA, JSON
RFCs, IETF, W3C, OCF
JSON, CBOR
Networks & Protocols IP/TCP based: HTTP(s)
WebServices, REST, WS, RTC
Web+= UDP: CoAP, MQTT
+ LPWAN, W/N/H/AN, NFC...
Hardware: CPUs: Desk/lap/top, mobile...
(GNU/Linux, Tizen, Android)
Web+= Microcontrollers
CPU, MPU, MCU
…. partially connected
Market penetration Massive: or Ubiquitous? 8.4B of devices (but low interop)
Developers adoption: +10M (Front/back, Javascript) Only ~3M (~1M Embedded)

Every project has challenges,
and every project has its rewards.
~Stephen Schwartz

Privacy is about Trust and Control
● Ownership of personal data
– Shared, Transferred, Revoked, Logged, Retrieved and DELETED
●
depend on time and context
● Services operators should comply regulations:
– EU: General Data Protection Regulation (GDPR 2018)
● Provider to inform, ensure security, share on consent
● User to acknowledge changes, revoke access
● Or FLOSS “Privacy by design” opportunities ?
– Prevent data collection in first place→Keep data local if possible
●
Limit usage of cloud, apps or “captive models”
● FLOSS: OpenId, Oauth2.0, JWT, PWA, WebBT, ACE, JOSE

Challenge: Rental property scenario
● House owner owns data (& metadata)
● Until a consumer rent it (contract)
– User should take ownership
● lights, door activities, or camera.
– Then user could aggregate data for owner
● Power consumption (on weekly base or on departure).
● Smooth integration with:
– Services: rental portal, social web
– Devices: Shared or personal devices

Demo: IoT gateway, ESP MCU, WebApp

● webthing-esp8266-webapp-20180602rzr

RESTful architecture
● From HTTP GET/POST to RESTful architecture:
– Verb (Create, Update, Read, Delete) on Subject
● Example: FLOSS: Mozilla IoT gateway
– Things models, described in JSON:
gateway="https://sosg.mozilla-iot.org" or "gateway.local"
thing="things/http---esp8266.local-things-dimmable-color-lamp"
property="properties/color"
curl "$gateway/$thing/$property"
-H "$auth" -H 'Accept: application/json'
{"color":"#ffff6f"}

Application layer adapted for low end devices
● CoRE: Constrained RESTful Environments
– CoAP: RFC 7252 Constrained Application Protocol
– HTTP/CoAP mapping, CBOR Serialisation.
● Base of framework implementing OCF spec
– for seamless connectivity between devices
– + IoTivity lite: low foot print for microcontrollers
– + IoTivity-node: for wrapping to JS using:
– Secured using DTLS (mbedtls)
– OpenConnectivity’s OneIoTA.org for common semantics

JavaScript: Language of the Web for IoT ?
● "Any application that can be written in JavaScript,
– will eventually be written in JavaScript." ~Jeff Atwood
● JS community is huge (Web, Node, NPM...)
● JS is portable: Browsers, Servers, Embedded
– Standardized Generic API and data models (JSON, JSON-LD):
● Ie: W3C generic sensors (that use I2C, analog drivers)
– Can run on even low end devices using JerryScript
● (RAM:64K+ROM:200K) Integrated in IoT.js, Zephyr.js, Tizen:RT
– Try: sudo apt install iotjs

From IoT to Web of Things
● WoT is Application Layer (OSI 7) rely on IoT Tech (1-6)
– Programmable: JavaScript, REST, WebSockets
– Shared Semantic: Data models to be exchanged (JSON-LD)
● W3C “Web of thing” introduces servient concept (server+client)
– App scripting
– FLOSS: ThingWeb: node-wot, Eclipse ThingWeb
● Mozilla “WebThings”: API and Gateway
– Network, Access, Find, Share Compose
● Challenges: Align semantics for Interoperability
– IETF, W3C, OCF and OGC

Summary
● Open Web ecosystem: massive adoption
● + Open Internet of Things: chaotic very heterogeneous
● = Open Web of Things: to link WWW to physical world
– aims to reduce integration complexity to developers
● open for applications or services
– desirable features: privacy by design (fix social web)
● Join FLOSS projects with open standards/specifications!
– JerryScript/IoT.js, IoTivity, W3C, MozillaIoT, Tizen...
