Multi channel sensor measurements in fog computing architecture

This paper presents the design concept of multi channel based sensing application at the physical edge of IoT network. The presented approach is based on reference Fog computing model, where sensor devices are connected to the edge fog node enabling the implementation of distributed real-time sensing applications. The proposed concept implies that the sensor data processing is relocated to the connected fog node, reducing hardware and power requirements of the sensor device. The reference fog node architecture, as well as application layer services for data communication, aggregation and processing are also provided.
