Mobile computing in the ‘bring your own device’ era

By Education, Technology, , , , , , , , , , , , , ,

Early in September Yale passed a milestone in mobile computing, with a record 39,414 mobile devices connected to its wireless networks. As on most college campuses the growth of mobile computing at Yale has been explosive, from well under 10,000 devices three years ago to almost 40,000 today.

A recent Gartner study showed that smartphone ownership among college students went from 55% in 2011 to 62% in 2012, and the percentage of students using their smartphones for academic work doubled in the same period. The typical U.S. college student now routinely uses between 2-3 wireless devices, and higher education computing experts predict that average to grow to 3-4 devices over the next year. (more…)

Researchers Boost Efficiency of Multi-Hop Wireless Networks

By Science, Technology, , , , , , , ,

Multi-hop wireless networks can provide data access for large and unconventional spaces, but they have long faced significant limits on the amount of data they can transmit. Now researchers from North Carolina State University have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.

“Our approach increases the average amount of data that can be transmitted within the network by at least 20 percent for networks with randomly placed nodes – and up to 80 percent if the nodes are positioned in clusters within the network,” says Dr. Rudra Dutta, an associate professor of computer science at NC State and co-author of a paper on the research. The approach also makes the network more energy efficient, which can extend the lifetime of the network if the nodes are battery-powered. (more…)
