Energy conservation theory in context aware computing

Awareness to the context is an energy consuming phenomenon. In the modern era of computing it is plausible to design a handheld device which can perform apparently to the higher level of energy conservation. Today Ubiquitous Computing is an evolving area of computing challenges. As per Ubiquitous Computing concepts it is totally based on context-awareness. Context aware systems consist with a large range of sensors which work on various levels of energy ranges. Those energy ranges consumes battery charge accordingly. So it is necessary to devise some vital techniques which have control over the energy consumption of battery and improving the on site performance of hand-held devices. Deliberating the performance of current hand-held devices, the extracted result is found that it give more time in sensing the context rather than sleeping. Hence some maintain the unbeatable accuracy on the cost of extremely energy consumption. Many times it is unnecessary to sense the context because the context is not changing with the corresponding time. Here the concept is to minimizing energy consumption while the sensors are not sensing the context.
