Re: [m2m-iwg] Google Cloud Messaging
|
Hi,
Thanks for the suggestions. We did experiment with GCM or a precursor (P2P communication between Android devices without needing to involve a central server) at an Android HackCamp meeting in Frankfurt. The working outcome was a PoC for an "Agile Plannning Poker", but I didn't analyze the underlying protocol that much at the time.
There could be a chance for a similar hacking lab in the next weeks anticipating Roskilde Festival in Denmark:
http://labs.roskilde-festival.dk/2013/05/idea-winners/#music-for-money this award-winning idea for a M2M style app is one of the 3 ideas that was selected by the community and everyone interested (and talented in that area) is welcome to implement a solution. The best ones will be deployed to the Roskilde site and also made available (for free) on Google Play. Whether this would be a P2P solution with such protocol, Bluetooth or rather along the lines of NFC (which may limit the devices and OS versions that can really use it of course
) is up to the developers. Of course any proper M2M protocol would be equally fine, as long as the available channels (P2P/Bluetooth, 3G or Wifi in some cases, at least next to a booth you may also find a Wifi node) can transport that without problems.
For the monetary aspect I am seriously considering JSR 354 or maybe a library like UOMo or even just ICU given all Android systems come with it. And unless currency conversion was required, a simple monetary value holder like ICU provides under the hood could be enough.

Has anyone compared Google Cloud Messaging with MQTT?

Completely different beast. GCM is for mobile push notifications to Android devices. One way, Android only, limited payload size, very different purpose (eg Facebook notifications to your phone).

These are two different types of Facebook notifications. MQTT is used
by Facebook messenger (for IM chats). GCM is used by the facebook
application to notify you when somebody 'writes on your wall' or when
you get 'tagged in a picture'. It is two completely different features.
