Remote Access to Physical Testbeds

  staff on experimental setup
• Scenario (environment, mobility, application
  etc.)
• System configuration (radio parameters, protocol
  set etc.)
• Data to be collected
• Application level (packet-by-packet,
  time-averaged etc.)
• Low layer metrics (SNR, PER, raw channel data,
  retransmissions etc.)
• Mobility

16
Measurement Data Repository

• Important to establish common networking
  scenarios first
• Creating a database indexed by the scenario type
