Intelligent Transportation Systems (ITS) is an important research topic. One goal of ITS is to exchange information among vehicles in a timely and efficient manner. In the ITS research community, Inter-Vehicle Communications (IVC) is considered a way that could achieve this goal without infrastructure support. An information network built on top of vehicles using IVC is a type of Mobile Ad hoc NETworks (MANET). In the past, many unicast routing protocols for MANET have been proposed. In these protocols, when a routing path breaks, they either locally or globally repair it. Because the topology of an IVC network changes very rapidly on the roads, an established routing path in such a network breaks very frequently.
