  1. Wireless systems and technologies I Current approaches to wireless vehicle communications Jack Pokrzywa Director Ground Vehicle Standards, SAE International

  2. Highlights from Presentation"A Vehicle Communication Scheme to Achieve Optimal Cooperative Positioning" • 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. Conclusions / Recommendations • 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

  4. Highlights from Presentation "Efficient Broadcasting, through Irresponsible Forwarding, in Intelligent Transport Systems" • Broadcast Protocols in VANETs • Efficient Broadcasting through Irresponsible Forwarding (IF) • Numerical Results • Improvements • Conclusions

  5. Conclusions / Recommendations • Efficient broadcast transmissions are a key factor in VANETs • Tradeoff between reliability, latency and efficiency • In safety related applications, latency is a critical issue • A correct but too delayed information has no utility • IF, with few adjustments, could be a solution

  6. Highlights from Presentation "Security Risk Analysis Approach for on-board Vehicle Networks" • Future vehicles will become mobile nodes in a dynamic transport network • vehicle systems will be under threat from malicious individuals and groups seeking to gain personal or organizational advantage • ensuring security will be critical for the successful deployment of V2X technology • EU project EVITA aims to prototype a toolkit of techniques and components to ensure the security of in-vehicle systems • hardware, software, analysis methods

  7. Conclusions / Recommendations • A security risk analysis approach has been developed from automotive safety and IT security practices • attack trees to identify asset attacks from use cases, attacker type and motivations • 4-component security risk vector, potentially including security-related safety issues • attack potential and controllability to assess probability of successful attack • Level and frequency of risks associated with asset attacks indicate priorities for counter-measures

  8. Highlights from Presentation "The Benefits of Enabling a Fully Autonomous Vehicle with Wireless Communications" • Automated, Autonomous,Communication-Enabled, and Cooperative – what do they mean • Case study presented: • Cooperative Sensor Sharing • Cooperative Cruise Control • Cooperative Convoy System • Mobility, Safety, Environmental impacts are reviewed

  9. Conclusions / Recommendations • The convergence of more aggressive active safety systems with more robust communication strategies will ENABLE the emergence of truly cooperative systems. • The more “autonomous” vehicles become, the more they will need to interact cooperatively with their surroundings (V2I and V2V).
