la-mqtt v1.0.1

Location Aware MQTT Protocol (la-mqtt)

About

The repo contains the source code of the la-mqtt project, an extension of the popular MQTT protocol for spatial-aware IoT communications.

In few words, la-mqtt enables to route the data generated by service producers only to consumers for which such data is relevant in terms of both topic and location; hence, it limits the amount of consumers to be notified to only the ones that are geographically inside the area of competence defined by the service producer.

Main features:

• Topic+Location based notifications
• Location privacy support
• QoS/privacy trade-off handling
• MQTT broker agnostic
• Fully backward compatibility with the standard MQTT
