A new software program, SleepWell, helps Wi-Fi -enabled smartphones manage downloads
and
battery life .
W-Fi is a major drain on batteries, especially around other Wi-Fi devices in the neighborhood
(or at Starbucks). In such cases, each device has to "stay awake" before it gets its turn to
download a small piece of the desired information. Researchers found that battery drainage
in downloading a movie in Manhattan is far higher than downloading the same movie in a
farmhouse in the Midwest.


Duke University-developed software eliminates this
Wi-Fi
drainage problem by allowing mobile devices to sleep while a neighboring device is
downloading information. This not only saves energy for the sleeping device but for competing
devices as well.


The new system has been termed SleepWell by Justin Manweiler, a graduate student in
computer science under the direction of Romit Roy Choudhury, assistant professor of electrical
and computer engineering at Duke's Pratt School of Engineering. The SleepWell system was
presented at the ninth Association for Computing Machinery's International Conference on
Mobile Systems, Applications and Services (MobiSys) being held in Washington, D.C.
