VANETS extend the driver's horizon to decrease traffic accidents by utilizing IEEE 802.11p wireless networks. In high density traffic situations an overloaded communication channel leads to significant packet loss. To overcome this problem multiple channels can be used in IEEE 802.11p. This itself leads to adjacent channel interference and impacts the(More)
Dual radios in Vehicular Ad-Hoc Networks (VANETS) enable the usage of multiple communication chan- nels simultaneously. This results in a higher network capacity in contrast to single radio setups. However, using multiple channels simultaneously leads to Adjacent Channel Interference (ACI) by generating noise in nearby channels. This noise increases the(More)
The detection of potential collisions between vehicles is one of the main functionalities of Vehicular Ad-Hoc Networks (VANETs). Vehicles periodically exchange beacon messages by using wireless communication. From the obtained information the receiver calculates the collision probability by predicting the potential movement of every neighbor. Due to the(More)
Cooperative awareness is established by vehicles exchanging their status frequently. In situations where a high number of vehicles access the communication channel with high frequency, communication and cooperative awareness suffer from increased packet loss. So far, forwarding of beacons focuses on extending the range of V2V communication which is not(More)
