> Many features that have been discussed as desirable in MQTT, or assist with its mission to be a lightweight pub/sub messaging transport are available in MQTT-SN, along with it being a binding of a very similar protocol to MQTT on a connectionless transport.
> MQTT-SN provides the following on top of standard MQTT features;
> Negative ACKs on publishes and subscribes
> Server initiated pings
> Server initiated disconnects
> Ability to update will message data at any point
> Topic Registration saves space when sending/receiving on the same topic and allows subscription identification of non wildcard subs.
> Will as part of session data
> Client controlled timed expiry of session data
> (along with other features specifically aimed at sensor networks)
> A lot of the above are compelling for the current implementation of MQTT over a connected transport, and essential if MQTT is looking to extend its usefulness in mesh/sensor networks.
