Data freshness, not speed, most important for IoT

Data freshness, not speed, most important for IoT

The age of sensor data is more important than how fast it takes that information to travel around Internet- and Location-of-Things environments, say some experts. Scientists are, in fact, rethinking the network because of it.

“It’s not enough to transmit data quickly. That data also needs to be fresh,” says MIT in a news release.

The university has been working on better ways to ensure that sensors, which distribute readings for analysis, provide the most salient stuff. It’s not easy because you can’t just send everything at the same time (an obvious solution) — there isn’t enough bandwidth.
