An Evaluation of Routing Protocols for Vehicular Ad-Hoc Network Considering the Video Stream

In promising application field such as Vehicular Ad hoc Networks, the ability of the driver to exchange video streams smoothly over the network regardless of his position is one of the most incentive features. However, dynamic nature of mobility and current obstacles in urban areas bring considerable challenges to routing. To give gratifying transmission performances, the vehicular networks must ensure Quality of Experience as well as keeping a tolerable Quality of Service (QoS). Furthermore, studying and comparing the efficiency of existing protocols have been challenging since each protocol is appropriate to a specific environment of application. Additionally, the lack in literature of quantitative comparison between the existing video stream requirements-based study, led us in this survey to analyze ten promising routing protocols focusing on communication challenges. Since the protocol chosen in the industrial world depends on certain metrics including video stream requirements, the paper shows also which protocols are suitable for MPEG-4 video quality by raking merits of QoS.
