There are several outstanding services envisioned for Vehicular Networks that require the provision of video dissemination support. These services range from enhancing safety via the dissemination of video from an accident scene to advertisements of local services or events. This work considers the infrastructureless scenario of Vehicular Ad Hoc Networks (VANETS). The dissemination of video content over VANETs is extremely challenging mainly due to the network's dynamic topology and stringent requirements of video streaming. This paper studies the main approaches aimed towards an effective and efficient solution for video dissemination over VANETs. Furthermore, some of these solutions have been selected to discuss their techniques and suitability for video dissemination and compare their performance. This work describes in detail the process of video dissemination over VANETs and presents a thorough evaluation of existing solutions. This permitted us to summarize our observations and indicate the direction for the design of new solutions.
