Acquiring and securing position information is of fundamental importance in vehicular ad hoc networks and their applications. Recently, it has been shown that securing position information can be achieved by enlisting the help of on-board radar devices that have seen a phenomenal penetration of the vehicular market. However, most on-board radar devices have a static range and this can cause a number...
Signal Strength based position verification is more promising as compared to other Sybil attack detection techniques because it is lightweight and does not require centralisation. Nodes can locally determine their locations through received signal strength variations and inform neighbours about location updates accordingly. In position verification, network nodes verify the position of each node and...
We describe an efficient method for positioning a vehicle in a noisy environment including malicious attackers and measurement errors. We assume the majority vehicles are honest and report the detection of position of other vehicles to provide vehicle position integrity in vehicular ad hoc network (VANET). The noise input includes bogus position information and position with measurement errors in...
