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 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
