Feasibility of an android messaging system using MQTT protocol

Is such a system feasible?

Can we implement features like: (all)

  1. User Access Control.
  2. Encryption of messages transferred.
  3. Predefined Topics.
  4. Message Logging(in a Database)
  5. Support up to 1000 users in the system.

Please help me out!

Let's look at these in relation to MQTT

  • User Access Control - handled by the broker, via a username/password on the CONNECT call. Implementations vary. IBM's commercial WMQ product provides a pluggable mechanism for auth, not sure about open source ones. If you want to encrypt the wire using SSL you could do so, again the commercial IBM implementation supports that, I don't believe the free options do.
  • Encryption of messages - needs to be done in the app, MQTT doesn't care what the payload is. There's some discussion of this online.
  • Predefined Topics - you define the topics your app uses and decide how to use them! there's no need to "predefine" anything from an administrative perspective.
  • Message Logging - simple to do via a backend script to subscribe to topics and push into a DB.
  • Support up to 1000 users - depends on the implementation, but yes. Again the commercial IBM implementation supports tens of thousands of concurrent connections, the free RSMB is limited to (I think) ~1100 connections... of course that's a count of connections rather than users.

I hope that helps. There's a good MQTT community at mqtt.org and mailing list available via mqtt.org/get-involved. There's a good news post discussing places where MQTT is being used on Android, too.

Feasible? Sure. None of the features you mentioned will really be in Android though, they'll be in your backend.
