>> IOTIVITY FRAMEWORK - STANDARD FOR OPEN SOURCE IOT
2015 will be the year a number IoT standards will be defined - question is;
will they stick?
IoT standards groups are working hard to establish solid foundations to
standardize how IoT devices will inter-operate - we have seen a number of
groups making efforts;
hosted by the Linux Foundation has made available a preview release of its
set of standards.
IoTivity version 0.9.0 release notes outlines the following components:
- device discovery and connectivity
- resource management
- virtual sensor management
- protocol plugin management
- things management
- smart home control management
- notification management
With support for devices using Linux, Tizen, Android (SDK API level 19),
Yocto and limited Arduino configurations. Communications using
are secured using
a modified version of the
library; that provides support for AES encryption with SHA256 - a
project that has previously been integrated into the Contiki operating system.
Of course; the project gets a little interesting when it comes to the
- a challenge for any of these standards efforts to be able to seamlessly
support due to limited resources available on the devices; promising to see
low powered devices are not forgotten.
The project currently only supports the Arduino ATMega 2560 and Due devices
with the Arduino Ethernet Shield (for communications); it will be interesting
to see support extended in the future to other low powered micro-controllers
- optimized for sensor end-points.
Unfortunately; it is still early days for these standards efforts - there
will be more published in the near future from various consortium groups
and depending on how well they are defined and maintained, it may be a
while - if at all if any of these become true standards.
