A use case for MEC

SimuLTE-MEC: extending SimuLTE for Multi-access Edge Computing

Car alert service

The car is approaching a black ice area:

  • On-board sensors
  • Vehicle-to-vehicle communications (VANETs)
  • Vehicle-to-infrastructure communications (Wi-Fi access to Road-side units)
  • Communication with a remote server

Implementing a MEC-based car alert service

  • UEWarningAlertApp – periodically sends position updates to the ME Host
  • MEWarningAlertApp – receives position updates from UEs
  • MEWarningAlertService – keeps the map of danger zones
  • WarningAlertPacket – includes position information
