VANET networks are classified as one of the applications of mobile case networks designed to improve road safety and provide passengers with comfort. Vehicle case networks are different in terms of architecture, features, challenges, and applications with mobile moving networks. Before many car networks are deployed, a number of technical challenges need to be addressed in order to exploit the benefits of these networks. Some of these challenges are common in car networks with other wireless networks, while others are due to the unique properties of car networks. In this research, we are trying to provide a new method for the exchange of information on highway roads based on the inter-car network. The main issues in this area are considering the distance between vehicles, type of protocol and standards. Also, modulation techniques, channel selection and channel replacement methods are based on weighted-based modulation, which explored in this research. Also SPA-(S, P) modeled in this work to optimizing more which applied to routing schema. This approach has been carried out in mountainous environments, especially in tunnels, and the results show improvements in the proposed approach compared to previous approaches in semi-mountainous roads rather than tunnels.
