A context-aware approach to conserving energy in wireless sensor networks

As sensor hardware technology proliferates, research in prolonging sensor battery life gains more interest. Conservation of sensor energy, therefore, becomes a practical approach to prolonging sensor life and eventually reducing the frequency of battery replacement. In retrospect, hardware-driven approaches have enabled significant power savings but on the expense of genericity as they are typical to certain sensor hardware. In this paper, we propose a software-based approach that is not contrained by sensor hardware and which is independent of any specific application domain. An implementation is done utilising the underlying framework and the results obtained validate our approach.
