Power-aware microsensor design

Military microsensors are networked distributed embedded systems composed of a processor, a radio, and sensors used for personnel or vehicle detection. They are most often found in minefield replacement and perimeter security applications where size, weight, power, and cost requirements are quite challenging. In this paper, we discuss the different system design approaches used in microsensor systems and introduce a modular, scalable, power-aware microsensor architecture intended span the entire dynamic range required of these systems. We describe a reference implementation of this concept and results from field experiments.
