Modeling and Simulation of Data Dissemination in VANET Based on a Clustering Approach

Abstract

Vehicular Ad hoc Network (VANET) is a specific type of Mobile Ad Hoc Network (MANET), which represents the main component of the Intelligent Transportation System (ITS). Sharing data and information among vehicles is an essential issue in VANET to cover all the possible events and accidents that can threaten human lives. This process is called Data Dissemination in communication. The VANET's applications require frequent floods of messages to improve the road's and passengers' safety. These messages are usually warning messages, which are forwarded to all or some vehicles according to the data dissemination models to warn the drivers about the expected disasters, accidents, and weather conditions. Data Dissemination represents a real challenge in VANET because of the frequent changes in topology and frequent fragmentation. Many protocols and techniques deal with data dissemination. This paper presents an approach that achieves data dissemination based on clustering and avoids a broadcast storm. A developed clustering approach is dependent on forwarded messages among vehicles. The proposed schema achieved good performance metrics.
