on IoT Protocols
It will always be a case of "AND", not "OR". The protocols
that solve actual interoperability and usage issues and make it
easier to build useful applications will succeed.
Personally I don't think XMPP and MQTT will dominate long
term because of fundamental limitations for usage in the IoT.
COAP is interesting but the binary focus creates a ton of
interop challenges.
Probably some evolution of COAP with richer metadata,
multiple protocol bindings, and expanded data and service
representations could succeed.
Very little if any new technology needs to be created to
realize a solid solution. It's really more of a people and
organizational challenge.
Hi,
I don't think this has been shared on the list before,
but here is [1] a nice reflection on protocols for M2M and
IoT. It's interesting to see how CoAP, MQTT, XMPP, … compare
with each other from a very high-level perspective. Also,
interesting to see that XMPP seems to be moving more and
more towards IoT (extensions for provisioning, sensor data
interchange, efficient XML interchange)…
"Connecting sensors and objects opens up an entirely new
world of possible use cases—and it’s precisely those
use cases that will determine when to use the right
protocols for the right applications."
