Abstract
A probabilistic method of determining a second vehicle in the VANET to which a packet is to be forwarded from a first vehicle is provided. The method includes determining the second vehicle to forward the packet from the first vehicle based on pre-calculated expected latency data corresponding to the second vehicle, and forwarding the packet from the first vehicle to the determined second vehicle. The expected latency data is indicative of the latency expected for communication of the packet from the first vehicle to the destination if the packet is forwarded from the first vehicle to the second vehicle, and is calculated in advance of the step of the determining the second vehicle to forward the packet. The second vehicle to forward the packet may also be determined based on pre-calculated communication probability data corresponding to the second vehicle in addition to the pre-calculated expected latency.
