Wireless sensor networks can optimize power usage in data centers

Narrator:          This is Science Today. Wireless sensor networks are tiny devices that measure such things as temperature, humidity, current and power. Raju Pandey, a computer scientist at the University of California, Davis, explains that these wireless networks can measure how much power is being used by servers.

Pandey:            And what that does is that allows you to start to make some sense of where the power is going. Is this power being used in the most efficient way? And once you have that information, then you can start to basically manage power. You can say, I have so much capacity, I'm using so much for this reason, I'm using so much for this reason. This is not a good reason, this is a good reason. So, you start to make the meaning out of how your power is being used and then you can start to optimize it.

Narrator:          Power usage in data centers is increasing significantly, so efficiency is a big concern.

Pandey:            If you can save energy in a data center, that translates into your capacity, too, because you don't need to build new data centers.
