Vehicular Ad-hoc NETworks (VANETs) have a highly dynamic network topology due to the constant and rapid movement of vehicles. Therefore, communication in VANETs is mostly affected with disruptions and delays as a result of network disconnections and partitions. Moreover increasing the geographical coverage area for data dissemination, keeping the data-delivery delay low is a challenge. This paper first surveys the routing techniques in Delay Tolerant Networks (DTNs), and also the usage of DTN communication in VANETs.
