In this paper, we show how tone mapping techniques can be used to dynamically increase the image brightness, thus allowing the LCD backlight levels to be reduced. This saves significant power as the majority of the LCD's display power is consumed by its backlight. The Gamma function (or equivalent) can be efficiently implemented in smartphones with minimal(More)
—As the current generation of mobile smartphones become more powerful, they are being used to perform more resource intensive tasks making battery lifetime a major bottleneck. In this paper, we present a technique called dynamic AoV lookahead for reducing wireless interface power consumption upto 50% while playing a popular, yet resource intensive, mobile(More)
The current generation of mobile smartphones are not just devices for voice communication. Instead, they are frequently used as mobile PC replacements that are used to edit documents, browse the web, check email, and play games. However, this functionality comes at the cost of battery lifetimes. Indeed, to maintain the slim form factor required for these(More)
—We present a low-complexity algorithm for intrusion detection in the presence of clutter arising from wind-blown vegetation , using Passive Infra-Red (PIR) sensors in a Wireless Sensor Network (WSN). The algorithm is based on a combination of Haar Transform (HT) and Support-Vector-Machine (SVM) based training and was field tested in a network setting(More)
—Applications on the smartphones are able to capitalize on the increasingly advanced hardware to provide a user experience reasonably impressive. However, the advancement of these applications are hindered battery lifetime of the smart-phones. The battery technologies have a relatively low growth rate. Applications like mobile multiplayer games are(More)
