Abstract

Exchange of geographical movement information is an important and potential life-saving feature for vehicular systems. By exchanging and processing their movement information, vehicles can easily detect dangers such as intersection collisions or notification of accidents ahead, thus improving the safety of drivers and passengers on the road. Many applications for active safety in Vehicular Ad-Hoc Networks (VANETs) operate in a decentralized fashion, namely by Vehicle-to-vehicle (V2V) communications without using any infrastructure. This paper describes such a kind of vehicular communication system that uses an efficient dissemination mechanism known as MHVB for the exchange of geographical location information at the network layer. The system targets active safety applications that have high requirements with respect to transmission delay and packet loss probability. The paper then proceeds to explain the process of communication that takes place between the nodes in the VANET. Finally we try to analyze the NS2 simulation results and provide some conclusions on the system.
