1. IoT challenge and methodology to address it

2. Case study: build a fire detection system w/o integration pain

Outline

As a device developer, you created an innovative thing…

Step 1: Connect the awesome device to the Internet

artik.cloud

A lot of options to implement a system where this device interacts with apps/things created by YOU

artik.cloud

Step 2: How to make it smarter?

• Interact with many other things from different vendors

• Customized integration is not scalable and not future proof

Today: IoT = collections of silo systems

artik.cloud

New Smart City Service

New Smart Building App

New Home Security Service

Not Yet Invented

Vision: Connect EVERYTHING and enable …

IoT = Interoperability of Things

artik.cloud

Realize vision: IoT Open data exchange platform

Any device Any cloudAny data

Data Sources Applications

New class of applicationsservices

Make connections, not silos.

Rich Open APIs

• Cloud is the best place to do it

• Three capabilities• Define and discover device Manifests• Powerful cross-device rule engine• Diverse ways to interact with devices and 3rd

party clouds

How to achieve interoperability?

Case study: Fire detection system using solutions from multiple vendors

Rules: IF fire is on/off, THEN turn on/off light

Now assume we are developers from Vendor A…

How can we build a fire detector device typeso that other developers can discover and use it?

Device development

Four steps for device development

1. Know your device data and capability

2. Define your device manifest

3. Obtain an access token

4. Make API calls: send data to or receive commands

Device dev (1/4): Know device data/capability

Device Dev (2/4):define device Manifest in the Developer Dashboard

Device Dev (3/4): Connect a device in User Portal

Device Dev (3/4) : Get Access Token

REST API call

POST: https://api.artik.cloud/v1.1/messages headers: {"Authorization": "bearer <DEVICE TOKEN>"}, body:{"sdid":"<DEVICE ID>", "data": {"temp": temperature, "onFire": onFire }, "ts": timeStamp }

Device Dev (4/4): Send data to ARTIK Cloud

https://api.samsungsami.io/v1.1/messages

Outline

Now assume we are developers from Vendor C…

How can we build an app to use device typesbuilt by others?

Application development

What does the app look like to an end user?

NO FIRE

Four steps for app development

1. Discover device type and learn data/capability

2. Create app and request permissions


4. Make API calls: get data from or send commands to

App Dev (1/4) : Discover device types

App Dev (1/4) : learn the Manifest


1. Discover device type and learn data/capability




App Dev (2/4): Create app and

request permissions


1. Discover device type data/capability




App Dev (3/4): get access token – OAuth2

https://accounts.artik.cloud/authorize? client_id=xxx&response_type=token&redirect_uri=android-app://redirect

android-app://redirect#expires_in=1209600&token_type=bearer &access_token=xxxx

Example: Step 1: make an authentication call

Step 2: catch callback to get the token

App Dev(4/4): get data from ARTIK Cloud

https://api.samsungsami.io/v1.1/messages/last?count=1&sdids=xxxxHeader: "Authorization": "Bearer <ACCESS_TOKEN>"

"data": { "onFire": false "temp": 80 }

Add Rules capability

Rules

Rule #1: If onFire is true, turn on lightRule #2: If onFire is false, turn off light

Two ways to manage rules• Manually manage them on User

Portal by the user • Programmatically manage them

through API calls within the app

Devices: • REST• WebSocket• MQTT• CoAP

3rd party clouds:• Cloud Connector• Subscription and

Notification• Integration using

REST/WebSocket

• Define and discover device Manifests• Powerful cross-silo rule engine • Diverse ways to interact with devices and 3rd party

clouds

Recap: how to achieve interoperability

• Build comprehensive solutions without integration pain• Each of the players focuses on what they do best
