Bridging GeoMQTT and REST

Wireless geo sensor networks (WGSN) use different ways to publish their measured data in the Sensor Web to make time series of this data accessible by means of the World Wide Web (WWW). In earlier papers, we proposed the use of GeoMQTT, a spatiotemporal extension to the widely known and used “Internet-of-Things” (IoT) protocol Message Queue and Telemetry Transport (MQTT). In this paper, we propose a GeoMQTT – Representational State Transfer (REST) bridge to enable users to easily interact with GeoMQTT by using standard HTTP methods. We demonstrate that using such a bridge is especially useful for debugging events issued by sensors nodes using GeoMQTT as a communication protocol.
