Many results have been published in the literature based on performance measurements obtained from simulations of vehicular networks (VANETs). These simulations use as input traces of vehicle movements that have been generated by traffic simulators which are based on traffic theory models. To our knowledge, no one has published any work based on actual large-scale recordings of vehicle movements....
Different attacks on routing protocols in ad hoc networks occur that one of the most dangerous types is called wormhole attack. This attack happens with the assistance of at least two or more malicious nodes. In this attack nodes create a private tunnel which if a packet comes to one of them, it will be guided to other pair of these malicious nodes by this tunnel and that node broadcasts it into network...

In this paper, we study group signature scheme for privacy preservation of a continually transmitting mobile vehicle. A moving vehicle transmits and receives different types of messages on the road. Such communication is a threat to the privacy of a vehicle as its communication can be used to link its identity to its physical entity. The change of size and nature of the neighborhood of a moving vehicle...
Vehicular ad hoc networks (VANETs) have received increased attention as the potential technology to enhance active and preventive safety on the road, as well as travel comfort. VANETs employ inter-vehicle and vehicle-to-roadside communications as means towards the reduction of the number of traffic accidents. On the other hand, intelligent traffic services are effective if they are associated with...
