Abstract
Broadcasting official and emergency information is seen as a principle role for controlling crisis situations. In fact, it has a great importance to ensure the communication between network nodes (vehicles, passengers, etc.). This paper presents a survey that examines the existing studies of broadcasting protocols. Our survey follows the guidelines of systematic literature reviews (SLR). It provides a comparison of the existing approaches based on some criteria such as communication technologies and simulation tools. Finally, we highlight some recommendations and possible future researches which need further investigations.
