WSO2 IoT Server

nogini.com is a manufacterer of fire safety devices.

Sumedha has purchases a fire alarm from nogini.com.

On top of the fire alarm, it says...

WSO2 IoT Server “For Server side IoT Architecture”

WSO2 Reference Architecture for IoT

WSO2 IoT Platform

WSO2 IoT Platform - Target Market● Device Manufacturers

○ Looking for software processing platform for new devices

○ Registering new device types

○ Device enrolment for device owners

○ Personalized dashboard for devices (device owners)

○ App building for device control

● Architects

○ Device Integration to existing solution architectures

● Part of WSO2 Cloud (App, API, Integration, Device - cloud)

○ http://cloud.wso2.com

WSO2 IoT Server

● Implementation of WSO2 Reference Architecture for IoT

● Offering WSO2 IoT Platform as a single distribution pack

● 1.0.0 GA - 2016 Q2

Middleware -> IoT Platform

Device Management Challenges

● Manufacturing Phase

● Deployment Phase

● Management / Usage Phase

● Troubleshooting Phase

Connected Device Management Framework

WSO2 IoT Server

Core Concepts

It’s a framework !!

**

Structure of Device Plugin● Plugin to CDMF

■ Currently an OSGI bundle● Controller API

■ API to send/receive control signals to device● Analytics Scripts

● UI component

**

IoT Device

● Piece of hardware● Built for a purpose● Capable of a limited functionality● Control interface● Input/output● Consumes power● Constrained Environment

Characteristics

Summary● Functional Capabilities (Actuators)● Administration Capabilities (Management)● Monitoring Capabilities (Sensor Data)

**

Modeling Device as an API

● eg : HTTP API (not limited to)○ Lock

■ GET http://{ip}/{locationid}/sensors/door1lock/staus■ POST http://{ip}/{locationid}/sensors/door1lock/lock

○ Temperature Sensor■ GET http://{ip}/{locationid}/sensors/temperature1

○ Motor■ POST http://{ip}/{locationid}/actuators/motor1/rotate/{turns}/{direction}

■ GET http://{ip}/{locationid}/actuators/motor1/status

**

Advantages - Devices as APIs● APIs - Standard Integration Pattern

○ Heterogenous devices■ protocols, access control mechanisms, data formats

● App Developers - Already familiar programming paradigm

● Seamless Integration with existing systems● Ability to re-user known patterns for securing, hardening

APIs● API Economy

Different modes of enrolment/registration

● COPE, BYOD

● Multifactor enrolment

● Dumb vs intelligent devices

● Self enrolment vs user enrolment vs bulk enrolment

Enrollment / enrolment ?

App / Firmware Managementpowered by

WSO2 App Manager

Supported Protocols

● MQTT

○ Topic per device instance

○ Single topic for IoT Server

● XMPP

○ Jabber account per device instance

● Web sockets

○ Device -> Event Listener -> CEP Output Adaptor (Web

Sockets)

● HTTP

○ HTTP server @ device gateway end

○ CoAP like

Security

● Token based authorization (OAuth2)

● Sharing (UMA)

■ Device owner sharing his device with someone

else

● Sharing device data

● Multi tenancy

Security Challenges

IoT Analytics

IoT Analytics

● How fast do you results?

● How much data to keep?

● Hindsight, insight, foresight
