Center for Embedded Networked SensingUpdate, October 2004
• 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)

• 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
• Time synchronization, Localization, Calibration, Energy Harvesting
• In Network Processing: Triggering, Tasking, Fault detection, Sample Collection
• Programming abstractions, tools
• Development, simulation, testing, debugging

NEON
“NEON will transform ecological research by enabling studies on major environmental challenges at regional to continental scales. Scientists and engineers will use NEON to conduct real-time ecological studies spanning all levels of biological organization and temporal and geographical scales.
(especially linkage to land)•Infectious diseases•Land use change•Land use change and •Material flux or processing
CLEANER: California regional effort
• A multiscale approach - San Joaquin River Basin: Water quality observation and forecasting--Sierra snowpack to San Franciso Bay
• Academics: UC Merced, UCLA, UCD, UCR, Caltech
• Govt Agencies: LLNL, LBNL, USBR, USGS, NPS, CA DWR
Key Accomplishments
• Multi-disciplinary research objectives– Cross-disciplinary teams deploying real
systems--Impossible without STC infrastructure
– Investigation of fundamental questions across our domains
– New areas of investigation:• Statistics, Data fusion (Hansen)• Programming languages (Kohler)• ELSI-ipercs effort (Cuff)
• Internal Organization:– Diversity and Education area growth– UC Merced partnership (Harmon)– NIMS Project
• Education– Very successful undergraduate
summer research program– 7-12 inquiry pilot testing– Gender-Diversity program
• Community/External visibility
– Co-Founded and hosted ACM Sensys 2004
– Co-Founded ACM Transactions on Sensor Networks
– Hosting IPSN 2005
– Soils workshop, JR Spring 2004
– Active in NEON, CLEANER planning
– Advisory to NSF CISE, ENG, ERE, and NRC panels
– Pottie-Kaiser, Cambridge Univ Press, Spring 2005
• Technology development– Emstar continued maturity– Stargate platform support– Nitrate Sensor, LC development– NIMS Lab system
• Testbed deployment– NIMS prototype:Wind River and JR– Factor building data capture– JR CMS, Phenology, ESS– Contaminant deployment--Palmdale– Marine lab facility– Marine field experiments-3-mike
