A Study on Communication System in VANET

VANET (Vehicle Ad-Hoc Network) is one of the new technologies in the communication system. It supports inter-vehicle communication through the 802. 11p.Many studies have looked at improving the quality of the communication system in VANET. Optimization and effectiveness issues in VANET are still open to exploration. Some researchers have used the natural-inspired algorithm to accomplish the issues in the VANET environment. Many tools can be used as a VANET simulator. While they are helpful, only some of these tools can be used for sophisticated analysis. It can support in-depth analysis or good graphical user interface features. But they cannot be thoroughly combined now. Each simulator has a different characteristic to produce a result. It helps to make a realistic traffic model in VANET. In this paper, we provide a brief information about the VANET communication systems, simulators and models.
