4 CONCLUSION
MQTT is an open source standard for M2M commu-
nication. Originally designed by IBM, the main use
for MQTT is as a publisher/subscriber protocol. In
this paper, we have introduced a new version, cal-
led MQTT-G, that adds geolocation information to
the protocol and offers a revised implementation, that
can help aid in the breadth of uses for MQTT. We
also modernize the protocol to include a somewhat
standard feature of most protocols in today’s IoT age.
The advanced protocol we implement can be used to
offer geolocation as part of the publish/subscribe in-
frastructure, thus aiding in the real time applications
that it can be used for. Our implementations offer ver-
sions for both its native C/C++ environment and as a
mobile Android client as well.
