Question

To minimize latency in a clinical monitoring system, which specific architecture allows raw sensor data to be filtered and summarized locally on the hardware before transmission to the centralized cloud database?

Accepted Answer

The specific architecture required is edge computing. In an edge computing architecture, data processing occurs at or near the physical location of the sensor, which is the network edge, rather than sending all raw data to a distant centralized cloud server. In a clinical monitoring system, this means the hardware device that captures physiological signals, such as heart rate or blood oxygen levels, performs initial filtering to remove noise and summarizes the data into meaningful insights locally. By processing the data on the hardware, the system reduces latency because it does not need to wait for a round-trip transmission of a massive volume of raw data to the cloud. Only the relevant, summarized information is then transmitted over the network to the centralized database, which saves bandwidth and allows for near-instantaneous decision-making. For example, a wearable heart monitor uses edge computing to detect an irregular heartbeat locally and immediately alert a physician, rather than waiting for a cloud server to analyze thousands of data points transmitted over a delayed internet connection.
