An Intelligent transportation system (ITS) focuses on application of smart vehicles. The vehicles are equipped with significant computing, communicating and sensing capabilities to provide services to travelers or the goal of providing safety massages in emergency situations. Vehicular network may also be used for Internet access, inter-passengers communications and entertainment. To understand the behavior of such networks as well as to provide good services to the travelers many issues have to be managed, some of them are: call handover between vehicles in vehicular network, speed Vs capacity, security of call, network topology, and network fragmentation. In this paper we study such vehicular networks and explain these issues and the related work. Detailed study of practical node mobility models based on mobility states and the quality of practical links based on received signal strengths are used as inputs for system capacity studies. Experiments were run in Sydney based on drive tests with mobile terminals deployed on them. Then some new ideas for managing the vehicular networks are proposed.
