Ideas

Terminology

  • Disaster Management: A set of actions and processes designed to lessen disastrous effects either before, during and after a disaster [11].

Requirements

  • Robust
  • Decentralized: No single point of failure
  • Cheap
  • Timeliness: Online and Real-Time
  • Opportunistic
  • Scalability
  • Networking interconnection (internal/external)
  • Self-organization
  • Unplanned (spontaneous) deployment
  • dependability and accuracy
  • Persistant storage
  • Priorization of processing tasks
  • ...

Application Domain: Early Warning for Earthquakes (Natural Disasters)

  • Possible areas: Istanbul, Bucarest, ...
  • Finely meshed network
  • Long distance interconnection
  • Online monitoring and processing
  • Alarming (Early warning, Interrupt supplies)
  • Storage of historical data
  • Before and after disaster infrastructure
  • Online shake-maps
  • Typical processing patterns??

Additional Services

  • public internet access,
  • email delivery
  • toll collection for the usage of roads
  • ...

OTS Hardware/Software

  • cheap COTS Router
  • cheap COTS Sensosr Hardware
