The amount of electricity used to power the Internet in the United States is equivalent to the output of two nuclear reactors. Professor Suresh Singh has identified ways to reduce this power consumption by as much as 70 percent.
It's part of a project he calls "Green Internet," funded by the National Science Foundation (NSF). By analyzing Internet traffic patterns he's found that router circuits can be selectively turned off to eliminate excess power usage without affecting the flow of data. As part of this effort, he's designing new Internet routing hardware as well as new software algorithms to run them. The work has piqued the interest of Intel, and is of great importance to developing countries with scarce power resources.
Making routers more efficient has other fringe benefits, Singh says. Greater efficiency means hardware can run at cooler temperatures, reducing the need for air conditioning and enabling the hardware to run faster and more efficiently.
Another NSF-funded project Singh is working on is called Rescuenet. It links high frequency radios to analyze and map the condition of partially collapsed buildings. The visual images inform search and rescue crews about a building's stability before they attempt to enter it.
