Data Fusion in Large Arrays of Microsensors (Sensorweb)

摘要

Distributed sensing by organized or self-organizing arrays of large numbers of geographically dispersed miniature sensors of various modalities is increasingly recognized as a key to battlefield surveillance. To date, research on data fusion in distributed sensing has often neglected physical constraints, including those on energy reserves, bandwidth, latency, processing capability and peak transmitter power. Fundamental limitations on data fusion and optimal strategies within these limitations, even under relative mild assumptions, are not yet known. The practical problem is that of devising algorithms that come close to the fundamental limitations with reasonable complexity. The FY2000 Multidisciplinary University Research Initiative (MURI) Data Fusion in Large Arrays of Microsensors (Sensorweb) will investigate these issues.
