Ubiquitous connectivity promises to make devices “smart”
But ONLY if they speak the same language

Network topology matters
Direct communicationis 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” of 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.

IoT Devices: how will they interact?
• IoT devices are characterized by the software they run so:– When IoT devices talk to IoT devices it is software talking 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
• APIs are how software talks to software

APIs – for IoT devices
• IoT devices should have APIs– But these IoT devices are all so different– Though often have very similar functions
• What APIs should IoT devices have?– Some standard APIs– Some device specific APIs
May 1, 2023 AllSeen Alliance 9
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
10
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

The AllJoyn™ Project
An Open Source Framework for the Internet of Things
May 1, 2023 AllSeen Alliance 12
December 2014 a group of companies formed the AllSeen Alliance• A nonprofit consortium dedicated to enabling the Internet of Things
• 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.
