2. What is cooperative positioning? How does DSRC help?
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
The Fully Networked Car Geneva, 3-4 March 2010

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. Broadcast Protocols in VANETs
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
The Fully Networked Car Geneva, 3-4 March 2010

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
The Fully Networked Car Geneva, 3-4 March 2010

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
The Fully Networked Car Geneva, 3-4 March 2010

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. Mobility, Safety, Environmental impacts are reviewed
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
The Fully Networked Car Geneva, 3-4 March 2010

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).
