MQTT-G: A Publish/Subscribe Protocol with Geolocation
Robert Mark Bryce, Thomas Shuler Shaw, Gautam Srivastava · 2018
Message Queue Transport Telemetry or MQTT is an open source publisher/subscriber standard for M2M (Machine to Machine) communication. This makes it highly suitable for Internet of Things (IoT) messaging situations where power usage is at a premium or in mobile devices such as phones, embedded computers or microcontrollers. In its original state, MQTT is lacking the ability to broadcast geolocation as part of the protocol. In today's age of IoT however, it has become more pertinent to have geolocation as part of the protocol. In this paper, we add geolocation to the MQTT protocol and offer a revised version, which we call MQTT-G. We describe the protocol here and show where we were able to embedd geolocation successfully.
