Programming the Internet of Things: Why Devices Need APIs
Download as PPTX, PDF8 likes2,362 views
The document summarizes an event hosted by the AllSeen Alliance about programming the Internet of Things using APIs. It discusses how devices need standard APIs to communicate across brands and platforms. It introduces the AllSeen software framework, an open source project that provides APIs to allow IoT devices to discover, connect and communicate with each other regardless of manufacturer. The event will provide updates on AllSeen and encourage collaboration among developers and businesses to advance open standards for the IoT.

- 2. 2 Ubiquitous connectivity promises to make devices “smart” But ONLY if they speak the same language 당신은 내 말 들려? Tem alguém aí? 100010101011hello world! hello world AutoHomeConsumer goods and appliances IndustrialComputing devices Devices that can’t connect across brands, categories, and operating systems will be left out

- 4. 4 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” NOW PLAYING: Artist: Flowers Song: Daisy “Someone’s at the door”

- 6. 6 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.
- 7. 9 September 2015 AllSeen Alliance 7 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
- 8. 9 September 2015 AllSeen Alliance 8 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
- 9. 9 September 2015 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. 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 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
- 11. 11 The AllJoyn™ Project An Open Source Framework for the Internet of Things
- 12. 9 September 2015 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.
