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

What is needed for a real-time data exchange
systems
  • System should be data neutral
  • Variable packet size
  • All formatting at application level
  • System should allow data query functions
  • System should allow dynamic updates of instrument
    metadata
  • metadata not embedded in every data packet
  • Packet descriptions should be available in
    real-time
  • Self-describing
  • Interoperable with other real-time data exchange
    systems and new real-time data sources

9
Design Goals for FutureReal-Time Sensor Networks
  • capture, process, control for quality, and
    integrate real-time data streaming from different
    sources--collected for different purposes, on
    different time and spatial scales, and measured
    by different methods
  • make heterogeneities in platforms, physical
    location and naming of resources, data formats
    and data models, supported programming
    interfaces, and query languages transparent to
    the user
  • adapt to new and changing user requirements for
    data and data products
