Vehicular communication systems are characterized by their high degree of mobility and the dependence on traffic density. High velocity in sparse networks usually create partitions that prevent the usage of traditional MANET protocols and algorithms. Nevertheless, the vehicles' mobility can be used to connect different sections of the VANET network. The DTN paradigm was specially designed for this kind of networks: the "challenged networks", that is, networks that do not satisfy the requirements of TCP/IP protocols to provide en-to-end connectivity
