1 Deborah Estrin http://cens.ucla.edu/Estrinhttp://cens.ucla.edu/Estrin destrin@cs.ucla.edudestrin@cs.ucla.edu Work summarized here is largely that of students, staff, and other faculty at CENS We gratefully acknowledge the support of our sponsors, including the National Science Foundation, Intel Corporation, Sun Inc., Crossbow Inc., and the participating campuses. Center for Embedded Networked Sensing Update, October 2004

2 Embedded Networked Sensing Micro-sensors, on- board processing, wireless interfaces feasible at very small scale--can monitor phenomena “up close” Enables spatially and temporally dense environmental monitoring Embedded Networked Sensing will reveal previously unobservable phenomena Contaminant TransportEcosystems, Biocomplexity Marine Microorganisms Seismic Structure Response

3 IT Challenges: Software and Algorithms Key Constraints: Energy awareness and conservation Scaling and adaptation to variable resources and stimuli Autonomous, disconnected operation Complexity of Distributed systems Technologies: EmStar TinyOS Habitat investigation, e.g NIMS (Networked Info- Mechanical Systems) Seismic detection, analysis arrays, e.g. CENS Seismic Array NIMS Seismic Target Apps: Technology Research: Self configuring systems for autonomy in dynamic, irregular environments In Network Collaborative signal processing and Event Detection for Scaling in time and space Exploiting System Ecology, Infrastructure, Mobility Multi-mode, multi-scale data fusion for tasking and interpretation

6 Inference in optical domain –CMOS technology: Low power ( capture < 40mA) –Cyclops is not imager but rather a sensor –Small picture size: Target below 256*256 Example Applications –Color estimation: Monitor triggering, Agriculture, Motion detection, Security –Low power, long term image archival: phonology Platform –Atmega128 8bit RISC PROCESSOR –512 KByte of Flash for local File system –512 KByte RAM Enough room for heavier computation Software and algorithm innovations –in-network processing of images for event detection –Limited resources, but in limited context Embedded Mote-based Imaging (Cycl o ps) Mohammad Rahimi

7 Identify and locate inter-specie and intra- specie of birds Use acoustical array to perform SNR enhancement for identification and localization Trigger imagers and human observers with solar-powered or short-term deployments Direction-of-arrival (DOA) algorithm used to calculate bearing crossings to locate bird(s) – Acoustic array based on Stargates, 802.11, Emstar software – Near-optimal Approximate Maximum- Likelihood based algorithm Sensor Arrays for Acoustic Monitoring of Bird Behavior and Diversity

8 System Ecology Including Mobility Spatially distributed static nodes Allows simultaneous sampling across study volume (dense in time, but possibly sparse in space) Limited energy and sampling rate Articulated Nodes Provide greater functionality for sensors, communications Nodes with infrastructure-based mobility: Networked Info-Mechanical Systems (NIMS) Sensor diversity: location, type, duration Allows dense sampling across transect (dense spatially, but possibly sparse in time) Adaptive provision of resources (sensors, energy, communication) Enable adaptive, fidelity-driven, 3-D sampling and sample collection
