ABSTRACT
A networked system of inexpensive and plentiful microsensors, with multiple sensor types, low-power embedded processors, and wireless communication and positioning ability offers a promising solution for many military and civil applications. As noted in Ref. [1], technological progresses in integrated, low-power CMOS communication devices and sensors make a rich design space of networked sensors viable. Recent years have witnessed several efforts at the architectural and circuit level for designing and implementing microsensor based networks (e.g., see Refs. [2–6] and the references therein). While architectural/circuit-level techniques are extremely critical for the success of these networks, software optimizations are also expected to become instrumental in extracting the maximum benefits from the performance and energy behavior angles. In particular, large-scale data management techniques (at the computation and communication levels) are very important [7].
