Grid meets sensors, sensors meet grid

Modern Grid systems use web services to interact with remote and distributed subsystem components to achieve an effective and common connection. Next generation Grid solutions will include instruments and sensors as part of the Grid, in addition to computational units (CE) and disk storage (SE). The Instrument Element (IE) is a new component that provides access to these remotely distributed pieces of hardware. The IE can organize generic devices in a "Grid of Instruments", providing a set of facilities to allow interaction between sensors and the existing classical grid infrastructure. In this paper, we describe the architecture of an Instrument Element system and present a collection of applications that successfully integrate and utilize this framework.
