Why Pursue an Adaptive Sensor Array? Advance existing sensing capabilities for research in complex, interwoven environmental and meteorological processes. Investigate, test and evolve emerging software methods designed for mesh network topologies. Develop application algorithms suitable for use and adaptation in other ATD instrument platforms. Deploy significant-numbers of cost-effective smart sensors capable of communicating, responding, and intelligently measuring diverse processes across heterogeneous environments (more measurements, at more points). Establish cooperative research relationships with outside agencies and universities (UCLA/CENS, CSU,..). Return to Top/Outline Slide

Development GOALS Augment and expand the RTF Integrated Surface Flux Facility (ISFF) with significantly extended / distributed environmental sampling coverage. Provide a ‘rapidly’ deployable platform that can be configured to facilitate straightforward relocation. Provide cross-habitat / mesoscale sampling combined with fine-scale sampling. Provide Internet access to real-time data stream Permit remote access for command and control of sampling systems. Provide ‘self-healing’ and ‘self-configuring’ array software capable of dynamically re-routing communications with extended ‘multi-hop’ peer-to-peer features. Explore, test and Incorporate promising technologies (Fuel-Cells, MEMS, Nano, Optical, etc.) as appropriate to further the over-riding need for low- power, small-scale, and overall research grade sensing products). Note: this level of effort would require a full commitment of personnel and financial resources and possibly a cooperating agency. Independent in-house development on raw low-level ultra-efficient components (such as MEMS based sensors) is unrealistic. Return to Top/Outline Slide

Preliminary Specifications Bi-Directional real-time Wireless communications. Flexible modular design capable of incorporating in-situ, remote, and 3-4D measurements of environmental, meteorological and chemical measurements in heterogeneous environments. (Cameras, GIS, etc.) A sensor that is both 'smart' and 'intelligent'. The 'smart' capabilities include processing, minimal calibration, connectivity, whereas the intelligent sensor will include diagnostics, predictive diagnostics, peer-to-peer communication, event response, and knowledge of past events. The design include the capability of gathering biological, chemical, physical and environmental data locally and remotely, incorporated with infrastructure knowledge for intelligent processing that includes triggering/activating internal and external devices, data rates, power management (to increase life of system), data quality, etc. Flexible long range (wide bandwidth)/short range protocol, that will minimize cost, include reliable communications, be compatible with legacy systems, provide appropriate communication ranges, be self- organizing/self-healing, and be power efficient. (IEEE Sensor Protocol P1451.2,3 and 4.) Multi-platform modular design capable of controlling and communicating with a variety of peripheral (PDA unit, Lap top, off the shelf sensors, planes, satellites, cameras, sniffers, etc.) or third party sensor The incorporation of the sensor intelligence to a self organizing network capable of continually connecting and re-connecting between local point and far nodes to optimise the efficiency and reliability of data including time synch and location. The ability to respond to both infrastructure and sensed events, i.e. stack plumes, etc., via power, data rate change, data calibration, network calibration, sensor calibration, etc. Return to Top/Outline Slide
