Vehicle movement, limited wireless resources, and lossy feature of the wireless channel make it is extreamly demanding to design an efficient routing protocol for vehicular ad hoc networks. The proposed protocol uses common backbone vehicles which are used for different traffic flows. It also employs interflow network coding to encode packets at the backbone vehicles. Vehicle movement dynamics and link quality between vehicles are the deciding factors for selecting a reliably connected backbone. Interflow network coding at the backbone vehicles helps the protocol to reduce the number of generated packets compared to the conventional routing approach. The main advantages are high packet delivery ratio, low overhead and low delay. Further reduction in delay can be achieved using compression techniques.
