A web of sensors: Enabling the Earth Science vision

Highly coordinated observations and autonomous decision-making are needed to improve our ability to detect, monitor, and predict weather; climate; and the onset of certain natural hazards. The 'SensorWeb' concept has been proposed as a potential solution to this requirement. This paper presents two candidate uses for the concept, describes its capabilities and unique architectural properties, and outlines challenges to overcome for successful development of SensorWeb architectures. The conclusion proposes that the primary challenge to implementation of SensorWebs—beyond the obvious technical obstacles—will be our ability to develop and execute a long-term strategy that provides for the deployment of a series of compatible missions that deliver the full promise of envisioned SensorWeb capabilities.
