SleepWell forces WiFi to wait its turn, keeps gadgets well-rested (update)

Ever feel like your WiFi devices' battery-lives are better off when not surrounded by peers and passersby? According to Duke University grad student Justin Manweiler and assistant professor Romit Roy Choudhury, this phenomenon is due to gadgets constantly fighting to retrieve the same data. Their Systems Networking Research Group has created a program dubbed SleepWell to alleviate the congestion; it puts WiFi to rest until the path is clear for accessing the specific data it needs, and provides improved power management all the while. The tech was shown off at MobiSys 2011 this past week and reportedly works well "across a number of device types and situations." Notably, Microsoft and Nokia (amongst others like Verizon) are backing up the project, which makes us cautiously optimistic that it could be headed for WP7 (or Windows 8, for that matter) in due time. There's no info on whether SleepWell will ever be distributed commercially, but may we suggest an LTE version to help out big V's poor ol' T-Bolt?

Update: We'd like to clarify that this software currently works from the accesss point side rather than the individual devices. You'll a find an additional PDF about the project in the source links below.
