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 V2V Market Share
