Modern computing is a continuum that runs from individual terminals and specialized embedded devices to the Cloud, passing through gateways and edge/fog computing nodes.A major challenge is the integration with the Internet of Things (IoT), especially with respect to sensor data acquisition, in an edge-to-cloud perspective. Despite novel approaches leveraging widely accepted standards have emerged for representing IoT objects and data, effective application-layer protocols for sensor data acquisition along the path from the edge to the cloud are missing. In this work, we propose SEAMDAP, an application-layer protocol enabling seamless sensor data acquisition for the edge-to-cloud continuum, based on standards for entity representations. We report the quantitative evaluation of a SEAMDAP-based system implementation, comprising an edge node and different IoT systems. The system was deployed in 2020 and thereafter has been supporting scalable sensor/satellite-driven services for wide-area Smart Farming applications.
