>> ALLJOYN - A CROSS PLATFORM MESSAGING FRAMEWORK FOR IoT
A flexible, dynamic and forward compatible framework for IoT communication.
The AllJoyn framework is an open source software system that provides an
environment for distributed applications running across different device
classes with an emphasis on mobility, security, and dynamic configuration.
It is “platform- and language-neutral,” meaning it was designed to be as
independent as possible of the specifics of the operating system, hardware,
and software of the device on which it is running.
It is designed with the concept of proximity and mobility always in mind -
in a mobile environment, devices will constantly be entering and leaving
the proximity of other devices, and underlying network capacities can
be changing as well.
Just reviewing the
member list of the alliance it is clear that there is significant backing
and a push for standardization in this area - unfortunately, it isn't the
only attempt out there and I doubt it'll be the last. At first glance the
AllJoyn standard looks great - the notion of independence and future proofing
is exactly what is needed to deal with a fragmentation issue that is bound
to be worse than any developers have seen in the past.
A recent article on
outlined the perfect use-case scenario that was demonstrated at CES in
Las Vegas earlier this year:
- A smart air monitor from Birdi, a startup, was placed in a room with several
other seemingly unrelated AllJoyn devices, including a television, speakers,
light bulbs, and a door lock - these were devices from manufacturers that have
had no idea of Birdi's existence. When the smoke detector detected smoke, it
used the home stereo speakers to sound the alarm, the connected light bulbs
started flashing different colors -- a visual alert for the hearing-impaired.
The television showed evacuation instructions, and the connected door
unlocked itself automatically.
By working with the standards defined within AllJoyn each component was
able to independently register with the AllJoyn Bus and exchange messages
as situations occurred - anyone listening on that bus that could handle
such messages could react accordingly.
The system is specified in quite good detail and an introduction to the
concept is available within the
available on the allseenalliance.org website.
