IoTivity vs AllJoyn - what is the difference?

Question

Open Interconnect Consortium has just released IoTivity, an open source framework for IoT, similar to AllSeen Alliance's AllJoyn framework. What are the differences between them, apart from IoTivity being based on CoAP and AllJoyn based on D-Bus? Are they interoperable?

Architecture

IoTivity

IoTivity provides 4 basic components:

• Discovery
• Data transmission
• Data Management
• Device management

AllJoyn

AllJoyn provides the following components:

• App Code
• Service Frameworks Libraries
• Core Library
• Router

It also provides the Thin variant without the Router.

Protocols

IoTivity

IoTivity will be using multiple protocols, but for now it uses CoAP. IT also has a MQTT plugin.

AllJoyn

AllJoyn provides its own bus based on D-Bus Wire protocol. AllJoyn Gateway Agent will have connectors for REST, MQTT, XMPP and TR-069.

Supported platforms

IoTivity

IoTivity currently supports:

• Android
• Arduino
• darwin/iOS
• Linux
• Tizen
• Windows
• Yocto

AllJoyn

AllJoyn currently supports:

• Android
• Arduino
• iOS
• Linux
• OS X
• Windows

Answer 2

One additional difference between these frameworks is how they treat Intellectual Property rights. AllSeen require from members not to sue other vendors which used AllJoyn for their product (Patent Non-Assertion Pledge).

Answer 3

Theyre completely different frameworks made by different companies that are both trying to achieve the same (or similar) thing. Its like comparing iOS to android.

They are not interoperable.

Answer 4

When it comes to supported transports, AllJoyn now supports more. It supports IP-related physical layers like WiFi, WiFi-Direct, Ethernet and Powerline. Also, it can support bluetooth with their gateway agent. Other radios such as Bluetooth LE, 6LowPan, ZigBee or Z–Wave are encouraged to be added.

Answer 5

Iotivity is easy to use, it provides C and C++ sdk for developing application on constrained devices. Quite easy to use for a basic application, provides GET,PUT ,POST and Observe functionality. Compared to Alljoyn it is faster and easier to develop apps on it.
