Advanced Networking Infrastructure and Research (ANI )

3. 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

4. Real-time Observatories Applications and Data management Network

5. ROADNet Development The Problem: … e.g.
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
