the network of physical objects or "uniquely identifiable things"

embedded with software, sensors and connectivity to enable it to

achieve greater value and service by exchanging data

without human interaction.

Internet of Things is…

Shortly called IoT…

Also called M2M(Machine to Machine)

Agenda

Why IoT?

What is IoT?

How to build IoT?

Tips

Why IoT?

Internet is everywhere

like electricity

wireless Internet is getting cheaper

Connectivity chips

#wifi

#3G

getting more affordable

On 2020

20-50 billion devices expected to be connected

7 devices per person!

Huge Business Opportunity

IoT Takes Over Big Data

As Technology

July 2014

Gartner’s 2012 Hype Cycle

Gartner’s 2013 Hype Cycle

Gartner’s 2014 Hype Cycle

What is IoT?

Real Life Examples

LG SMART THINQ

Works with Smart Grid

Works with

What if Apple made a Car?

Tesla Car

Detect repairs

Schedule fix Autonomously

Connected Car

IoT Components

IoT ComponentsDevices

Sensors

MCUs

Small Computers/Smart Phones

Gateways

Network

Media and Protocols

Middleware / IoT Platforms

Cloud

Storage (SQL, NoSQL)

Web apps, APIs, analytics, …

Architecture of ARM mbed

How to Build IoT?

Devices

MCUs

Arduino

Microduino

TI Launch Pad

Spark Electron

Spark Electron

(IoT for folks)

Spark ElectronArduino-like cellular development kit

Open Source HW & SW

$39/board

$3/Month Data plan

Monitor soil moisture

Small ComputersRaspberry Pi 2

$35

900 MHZ quad-core

1 GB RAM

HDMI, …

Big community

Small Computers

BeagleBone Black

Intel Galileo (Arduino based)

OS for DevicesContiki-OS

Designed for IoT (Memory, Protocols, Battery)

Open Source

Raspbian

ARM mbed OS

Linux/*nix,…

Network

Network

Media and Protocols

Wired?

Wireless

Everything is going wireless So is

The Internet of Things

Wired Ethernet is almost obsolete!

Wireless NetworkingWiFi (Battery Hungry)

BLE (Great for PAN)

GSM

Works for many use cases

$$ for large # of devices

Other Wireless NetworkingZ-Wave

ZigBee

6LoWPAN

LoRa

ZigBee Vs BLEZigBee

WLAN (Home Automation)

Mesh topology covers unlimited # of nodes

Sense & Control apps

BLE

PAN

Star topology covers limited # of nodes

Body and Peripherals

LoRaLong Range

2+ Miles Range In Dense Urban (NLOS)

Low Power (Multi-Year Battery)

One Gateway support 10(s)K Nodes

Data Rates < 300 kbps

Libelium's LoRa module

Non Line Of Sight (NLOS) Tests

Middleware

Agenda for MiddlewareProtocols

Data Transfer

Device Management

IoT platforms

Standardization

Data Protocols

Data ProtocolsHTTP

MQTT

CoAP

AMQP, STOMP

WebSocket

MQTTPublish/Subscribe

Lightweight (than HTTP)

IBM says “MQTT can send messages wirelessly using 10 times less battery power and 93 times faster"

Best for:

Low Bandwidth

Unreliable Network

CoAP

RESTful design

Feels like HTTP

Lighters than HTTP

Best for: MCUs 10 KiB RAM

Device Management Protocols

Device Management Protocols

Manual Approach

TR-069

OMA-DM

OMA Lightweight M2M

OSGi

Manual ApproachUpdate Device

SSH login/run script remote

Or Pull changes using git

Device monitoring

Send heartbeats to custom web service

Manual Approach

Pros

very lightweight

Cons

reliable, scalable?

OMA-DMProvisioning

Configuration of the device (including first time use)

Enabling and disabling features

Device Configuration (change device settings & parameters)

Software Upgrades

Fault Management (Report error, status)

Open Source implementations available

OMA Lightweight M2MSimple, efficient protocol

Banking class security (DTLS, …)

Supports Cellular, 6LoWPAN, WiFi and ZigBee IP or any other IP-based devices

Open Source Implementation

OSGiAn open standard service platform for Java

Enables dynamic component model (bundles)

Bundles can (remotely without a reboot) be:

installed/uninstalled

started/stopped

updated

OSGi Other Features

Run on low power hardware 156 MHz and 8 MB RAM only

Many commercial/Open Source Implementations

Tips

TipsThe IoT is Huge

Many challenges!

Many technologies/protocols

Design for Best Fit

Determine your hardest problem

Choose the primary protocol/tool to solve it

Tips

A complex system can use more than one protocol/tool

Support standard IoT protocols

Use time series NoSQL/Big Data

Tips

Security is not an option

Scalability & APIs

Sandbox/testing environment

Software And Hardware Together

iOS + iPhone

vs

Android + LG +Samsung + …
