Furthermore, video streaming is affected by VANET features, such as the high dynamic topology, fluctuation of vehicle density, and environmental obstacles. In VANET, video streaming can be achieved by using different VANET communication types, such as V2V (Vehicle To Vehicle), V2I (Vehicle To Infrastructure), and V2X (Vehicle To Everything). Based on these communications, the vehicles can exchange between them the video stream in a single or multi-hop manner. In VANET, the vehicles applied a routing protocol in order to disseminate the video stream through a path (s) between the sender and the receiver (s) vehicles. In this study, we have reviewed and discussed several studies on routing protocols for video streaming in VANET. An overview of popular existing routing protocols, such as AODV, AOMDV, DSR, DSDV was presented. Furthermore, we have evaluated and compared these protocols in terms of routing performance, such as E2EDelay, throughput, and PDR based on vehicle density in order to judge which one is outperforming in video streaming over VANETs. The simulation results show that the AODV routing protocol is better than AOMDV, DSR, and DSDV in terms of throughput and End-to-End delay but unstable in PDR. In general, the significance of these results is that the reactive routing protocols AODV, AOMDV, and DSR are more effective than the proactive routing protocol DSDV, in reverse the latter is more stable than the other ones.enVideo streamingRouting protocolOther
