The Complex IoT Equation (and FLOSS solutions)

  1. 1. Samsung Open Source Group 1 #OW2Con @ http://sched.co/Ecdl The Complex IoT Equation Philippe Coval Samsung Open Source Group / SRUK p.coval@samsung.com (and FLOSS Solutions) #OW2Con, IoT Track Paris, France <2018-06-07>
  2. 2. Samsung Open Source Group 2 #OW2Con @ http://sched.co/Ecdl 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
  3. 3. Samsung Open Source Group 3 #OW2Con @ http://sched.co/Ecdl Agenda ● State of the art – Learn lessons from success of WWW ● Some IoT challenges – Privacy & Interoperability ● From IoT to Web of Things ● More...
  4. 4. Samsung Open Source Group 4 #OW2Con @ http://sched.co/Ecdl “Out of clutter, find simplicity.” ~Albert Einstein
  5. 5. Samsung Open Source Group 5 #OW2Con @ http://sched.co/Ecdl 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
  6. 6. Samsung Open Source Group 6 #OW2Con @ http://sched.co/Ecdl 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)
  7. 7. Samsung Open Source Group 7 #OW2Con @ http://sched.co/Ecdl Every project has challenges, and every project has its rewards. ~Stephen Schwartz
  8. 8. Samsung Open Source Group 8 #OW2Con @ http://sched.co/Ecdl 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
  9. 9. Samsung Open Source Group 9 #OW2Con @ http://sched.co/Ecdl 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
  10. 10. Samsung Open Source Group 10 #OW2Con @ http://sched.co/Ecdl Demo: IoT gateway, ESP MCU, WebApp https://youtu.be/vzoUJ-v5h38 ● ● https://vimeo.com/273037442 ● webthing-esp8266-webapp-20180602rzr ● https://youtu.be/vzoUJ-v5h38 ● https://vimeo.com/user12599872/ ● webthing-esp8266-webapp-20180602rzr
  11. 11. Samsung Open Source Group 11 #OW2Con @ http://sched.co/Ecdl 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"}
  12. 12. Samsung Open Source Group 12 #OW2Con @ http://sched.co/Ecdl 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
  13. 13. Samsung Open Source Group 13 #OW2Con @ http://sched.co/Ecdl 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
  14. 14. Samsung Open Source Group 14 #OW2Con @ http://sched.co/Ecdl IoT.js on TizenRT: Sensor+LoRaWAN demo https://youtu.be/S7zpBpnpflU#tizen-rt-lpwan-20180204rzr ● https://vimeo.com/273037442#
  15. 15. Samsung Open Source Group 15 #OW2Con @ http://sched.co/Ecdl 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
  16. 16. Samsung Open Source Group 16 #OW2Con @ http://sched.co/Ecdl 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...
