The data dissemination is a method of flooding the messages to a group of vehicles at a time. The convention data dissemination models are categorized into push, pull, and hybrid. The push-based data dissemination models utilize periodic broadcasts, widely used for safety-related emergency VANET applications. The pull-based models employ on-demand broadcast, and it is used for a comfort application. Some work combines the advantages of both push and pull models to meet the application-specific VANET requirements.
