Low power, high performance sensor designs are of particular importance nowadays considering the plethora of emerging applications in a wide range of fields. Applications such as audio capture, FFT (Fast Fourier Transform), image sensing, motion detection, feature extraction and cepstrum calculations generate raw data in much larger quantity than more mundane applications as temperature and humidity sensing. In-situ processing of data is an effective way to reduce the amount of information needed to be transmitted over the wireless links. The Co-S platform which we develop addresses this very crucial aspect of sensor network design. The Co-S integrated with a System on Chip (SoC) based host platform and a gigabyte scale energy efficient data storage system, simultaneously satisfies the constraints of low power consumption and a small form factor. As opposed to the Sense-and-Send approach which simply entails transmission of raw sensory data from the nodes, the proposed Sense-and-Store paradigm, builds upon the availability of the low power flash memories for storage of sensed data along with key query results (max, min, average, extracted harmonics) for transmission through the network. This approach not only reduces energy consumption (typically two orders of magnitude), of the sensing node in question, but also intuitively reduces network traffic load vis-à-vis complete deployment scenario. © 2005 IEEE.
