What is a Vehicle-to-Vehicle Network?

GrooveNet::Modular System Design

  • Event-driven Simulator:
  • Simulates vehicles on any city street map
  • Supports multiple traffic incidents in real-time
  • Peer-to-peer network for vehicles on the road
  • Multi-hop wireless communication between vehicles
  • Real-Time Safety Alerts can save lives
  • Online Traffic Probing can shorten commutes & conserve gas
  • Simulation Models:
  • Includes more than 10 traffic and communication models
  • Easily develop and integrate new models

On-Road Vehicular Network Testbed

  • GrooveNet supports >5,000 simulated vehicles
  • Scalable topography-accurate simulations of V2V networks
  • Shortens time-to-market for V2V communication systems
  • Vehicles drive and communicate on any US street map
  • Easy To Use
  • Creating large, complex simulations was never easier!
  • Connects real and simulated vehicles for robust and large-scale testing of V2V network protocols
  • On-Road Test Setup
  • Deployed across 5 GM vehicles
  • Connected to GPS, wireless interface, voice and video for real-world tests
  • One platform for both real-world tests and simulations

Geographic Routing for Safety Alerts

How close are we to V2V?

  • Messages broadcast within well-defined geographic regions
  • Safety Alerts travel 3-5 miles within seconds
  • Message delay is a key performance metric
