  1. Vehicular Communication and Optimal Cooperative Positioning Asghar Tabatabaei Balaei University of New South Wales

  2. Outline • DSRC • How does GNSS work? • Why is GNSS not enough? • What is cooperative positioning? • How does DSRC help? • Effect of network parameters on positioning performance • Precise position and reliable Communication

  3. Dedicated Short Range Communication (DSRC) • High-speed, short-range, low-latency wireless communications between vehicles • IEEE 802.11p standard for wireless access in vehicular environments • Rapid connection establishment and network acquisition • System Components • onboard units (OBU) • Road side units (RSU)

  4. How does GNSS work? • Multilateration • TOA • At least four satellites with atomic clocks • Global coverage • Unlimited number of users GNSS Signal Environmental noise

  5. Why is GNSS not enough? GPS RF Interference

  6. Cooperative Positioning

  7. How dose DSRC help? Localization Block On Board DSRC Unit Monte Carlo/Particle Filter Estimator Ranging & GPS Block Memory Adhoc Information Communication Block Computation Unit

  8. How Dose DSRC help?

  9. Effect of network parameters on positioning performance

  10. Precise position and reliable Communication

  11. Summary • Cooperative Positioning is needed to improve the positioning accuracy in the vehicular environment • Communication constraints affect the level of accuracy that we can get from cooperative positioning
