ABSTRACT

The Vehicular Ad-hoc NETworks (VANET) consist of a spontaneous association of a group of vehicles with wireless connection, they move and dynamically change their positions, exchanging data between each other. These networks were thinking as autonomous network segments with flat addressing schemes, however, its study has shown the benefits obtained by interconnecting them to fixed network segments and Internet. This article will revise by means of using a simulation tool, the global improvements in QoS network metrics, achieved through the use of a mutipath routing protocol. The model has a fixed network segment (Internet), two reactive gateways and two IPv6 VANET hierarchical network segements, whose nodes show a high degree of mobility, such as vehicles in an urban environment.
