And that platform is about to be dwarfed…

Massive surge in connected things has already begun

By 2020, 40.9 billion things will be connected*

− Via Wi-Fi, wire line, cellular, and proximal networks − Benefiting billions of people worldwide − 75% of the growth between today and the end of the decade will come from non-hub devices

Transforming:

− Industry − Infrastructure − Media − Education − Work − Recreation − Family − Daily life

Ubiquitous connectivity promises to make devices “smart”

But ONLY if they speak the same language

당신은 내 말 들려?

Tem alguém aí? 100010101011 hello world!  Auto Home Consumer goods and appliances Industrial Computing devices

Devices that can’t connect across brands, categories, and operating systems will be left out

6

Network topology matters

Direct communication is fast, efficient, and secure. No need to go out to the cloud to talk to the device right next to you!

“Coffee is done” “Coffee is done” “Laundry is ready!” “Laundry is ready!” “Someone’s at the door” “Someone’s at the door”

What are these “things”

• f which you speak?

Without the right combination of hardware, connectivity and software a “Thing” is just a “Thing”. Ultimately it is software that makes a “Thing” an Internet-of -Things Thing.

APIs - how software talks to software

• Well constructed software has clean boundaries between the internals of the

implementation and the external interfaces exposed to other software.

– We generally call these external interfaces Application Programming Interfaces (APIs) – APIs are what makes it possible to incorporate existing functionality into new code

• Software platforms are simply collections of APIs

– Windows, Linux, Android, iOS, OSX – are defined by the APIs they provide – Examples abound - OpenGL, PhysX, Webkit, every social network on the planet!

APIs – for IoT devices

• IoT devices are characterized by the software they run so:

– When IoT devices talk to IoT devices it is software talking to software

• IoT devices should have APIs

– But these IoT devices are all so different – But often have very similar functions

• What APIs should IoT devices have?

– Some standard APIs – Some device specific APIs

11

IoT needs a framework to expose the various APIs of connected devices in a consistent way.

A single platform allowing products to expose their capabilities

LOCK DOORS LIGHT BULBS GARAGE DOOR SENSORS PICTURES VIDEO DRAPES DISPLAYS SPEAKERS CLOCKS COOL HEAT TVs

The AllJoyn software framework is a collaborative open source project of the AllSeen Alliance

12

Devices describe their capabilities via discoverable self-describing service interfaces

I can send notifications I have control panel I have lighting interface I can send notifications. I have control panel I have a clock interface I display notifications. I have the clock interface! I display notifications. I have the clock interface! I display notifications. I have the clock interface! I can send and display notifications I can send notifications

Standards

• What we don’t want:

– There’s an App for that thing – And an App for that thing – And yet another App for that thing – …

• Devices that have similar functionality should expose the same APIs

– Every device with a clock should expose a set-clock API – Every device that has a battery should expose a battery level API – Manufacturers cannot differentiate by exposing necessary functionality in different ways

14

Exposing smartphone APIs enabled new experiences - that no one had ever thought of

15

The problems to be solved…in an open interoperable way

DISCOVER nearby friendly devices IDENTIFY services running

• n those devices

ADAPT to devices coming and going MANAGE diverse transports INTEROPERATE across different OSes EXCHANGE information and services SECURE against nearby bad actors

Baseline for an API framework for IoT

• Must be designed to work with existing programming languages

– Java, C, C++, C#, JavaScript, Python, etc

• Must support modular construction

– To allow standard building blocks – To allow innovation

• Must include facilities for discovery

– Find out what APIs a device has rather than what the device is

• Must support privacy and security

– Which APIs can be used by other devices – Authentication and data encryption

The AllJoyn™ Project

An Open Source Framework for the Internet of Things

2 December 2014 AllSeen Alliance 18

A year ago a group of companies formed the AllSeen Alliance

• A nonprofit consortium dedicated to enabling the widespread adoption of products, systems and

services that support the Internet of Things through an open environment, vibrant ecosystem and thriving technical community.

• Hosts and advances an industry-supported software and services framework based on the

collaborative AllJoyn open source project.

• This collaborative open source framework enables hardware manufacturers and software

developers to create interoperable products that can discover, connect and communicate directly with other devices, systems and services regardless of brand.
