Abstract: Vehicular Ad Hoc Networks is a part of wireless ad hoc network that it has the characteristics of high node mobility and fast topology changes. The Vehicular Networks can provide wide variety of services, ranges from safety and crash avoidance to Internet access and multimedia applications. These vehicular communication problems include network architecture, protocols for physical and link layers, routing algorithms, as well as security issues. In this paper, we deal with the multiple issues in the vehicular ad hoc network communications and solution about these problems.
