An edge computing node at a sensor site filters out invalid readings and calculates hourly summaries before sending data to the cloud. A sensor reporting every 10 seconds generates 360 readings per hour, but only a single hourly summary is transmitted. What is the primary operational benefit of this approach beyond bandwidth reduction?

Question

Accepted Answer

If the internet connection to the cloud fails, the edge node continues performing threshold checks and issuing local alerts, maintaining monitoring capability during the outage

Answer

The edge node improves the accuracy of sensor readings by applying calibration corrections locally

Answer

The edge node reduces the purchase cost of sensors by handling part of the measurement process

Answer

The edge node encrypts data before transmission, improving security compared to cloud-only processing
