摘要：In the 2000s, ad hoc networks was developed and highly used in dynamic environment,particularly for inter- vehicular communication (VANETs : Vehicular Ad hoc Networks).Since that time, many researches and developments process was dedicated to VANET networks.This was motivated by the current vehicular industry trend that is leading to a new transportsystem generation based on the use of new communication technologies in order to providemany services to passengers, the fact that improves the driving and travel’s experience.These systems require traffic information sharing and dissemination the example as the casealert message emitting allowing the driver to minimize driving risks. Sharing such informationbetween vehicles helps to anticipate potentially dangerous situations, as well as planning betterroutes during congestion situations.In this context, we are trying in this paper to model and simulate VANET Networks in order toanalyze and evaluate security information dissemination approaches and mechanisms used inthis type of networks in several exchanges conditions.This in order to identify their limitationsand suggest a new improved approach. This study was conducted as part of our researchproject entitled “Simulation & VANETs”, where we justify and validate our approach usingmodeling and simulation techniques and tools used in this domain.
