The Vehicle Ad-hoc Network (VANET) represents a developing and emerging intelligent transport technology (ITS) technology that allows interaction between vehicles (V2V) through various IEEE standards, such as IEEE 802.11p. VANET's high mobility of nodes generates major challenges when routing packets through the main target node that must be addressed with various routing protocols. Take that into consideration. In this review paper, we study three sections to describe this review. In the first section, we will explain the principle of data dissemination. In the second section, we will classification and explain the routing protocols for all their types. Finally, we will discuss the challenges for VANETs, data dissemination, and routing protocols.
