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

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 The Fully Networked Car Geneva, 3-4 March 2010

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

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

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

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 The Fully Networked Car Geneva, 3-4 March 2010

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

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). The Fully Networked Car Geneva, 3-4 March 2010
