RWTH cooperation
Team: Lothar Stibor,Yunpeng Zang, Dr. Rokitansky
• Channel and mobility model integrated into WARP2
(SDL) simulator (world first 802.11p MAC simulator)
• Highway and rural intersection scenario simulations
• Congestion avoidance for broadband VANET using
beaconing for scheduled TxOp's (VWMN)
• Congestion control for 802.11 compatible solutions
• IEEE 802.11p and IEEE 1609 contributions & IPR

Simulated Scenarios
• Average car density
– message forwarding algorithms
– Coverage of the zone of relevance
– Stability of neighbourhood relations
– Hello message repetition rate
• High vehicle speed
– Communication with oncoming traffic
• Low equipment rate scenario
– Determination of minimum necessary
equipment rate
• Traffic jam
– congestion control algorithms
• Discarding of outdated warnings

Business Implications
• US tolling drives 802.11p roll out
• Government/legislation needs successful
deployment before investing in infrastructure
• Low-penetration applications need large
coverage or municipal Wi-Fi
• Connected Car competes with Connected
Driver (TomTom plus OBD2 via Bluetooth)
• Proven Security/Privacy solution is a Must
