For the most part, when someone is on the move in a fast moving vehicle they depend on the 3G cell network (or 4G if they’re lucky) to provide their data connection.  The problem is one of pricing, as utilizing the cellular network to move any amount of data tends to add up to a noticeable expense over time whereas WiFi tends to be free.  Enter Wiffler, a “prediction based offloading” program that is intended to allow you to offload at least some of your data transfers onto WiFi.  The program will hopefully allow a WiFi/3G combo neteork while you are driving or otherwise non-stationary.  Click through the link at Slashdot to find out more.

“Researchers from Microsoft and the University of Massachusetts have been working on a technology that would let mobile phones and other 3G devices automatically switch to public WiFi even while the device is traveling in a vehicle. The technology is dubbed Wiffler and earlier this year its creators took it for a test drive with some interesting results. Although the researchers determined that a reliable public WiFi hotspot would be available to their test vehicles only 11% of the time, the Wiffler protocol was able to offload almost 50% of the data from 3G to WiFi.”
