Research (ANI-0087344)

Lessons from HPWREN

• Interdisciplinary projects are extremely beneficial– Need cross-disciplinary understanding to make progress

• Measurement analysis to assess and adapt system– Bandwidth constraints

– Prioritization - QOS

• Testbed for operational and prototype sensor networks– Use existing wireless and networking technologies whenever

possible

– Wide range of climate and environment

– Innovate and develop sensor connectivity and processing

– Variety of testbeds needed for next generation wireless

and networking

ROADNet DevelopmentROADNet DevelopmentROADNet DevelopmentROADNet Development• The Problem:

– Integrated real-time management of large, distributed, heterogeneous data streams from sensor networks

• … e.g.– integration: handling of heterogeneous data from multiple

(signal) domains, interfacing with sensors and data loggers to acquire streams

– real-time processing: monitor streams of data, detect events, trigger computations and other actions

– distribution: federate multi-domain sensor and embedded system networks for transparent access

– persistent large-scale archival and querying of “consolidated” data packets
