We present an OPNET model that uses WiMAX technology to send video packets in an advanced inter-vehicle VANET environment. Our work focuses on real-time video streaming. A video model was created based on live traffics trace and then integrated into a WIMAX OPNET model. VANET mobility was modeled with a real world road map and VANET mobility simulators. We integrate an implementable controller over RTP to handle congestion control by setting a framework fit for future road safety development. Different mobility cases are studied and the performance measures such as end-to-end delay, jitter and visual experience are evaluated. Different design considerations are presented to enable designers to effectively build on and develop a realistic video VANET simulation model.

VANET (Vehicular Ad-hoc NETwork) is a subclass of MANET (Mobile Ad-hoc NETwork). Since nodes in a VANET are usually high-speed mobile vehicles, the network topology changes so fast that conventional routing protocols, especially those designed for quasi-static network topologies, do not work well in a VANET. Since vehicles with GPS receivers and Digital Map devices are now widespread, routing protocols based on real-time traffic conditions emerge. In the routing protocols, road intersections form the virtual backbone. In particular, there is a connection between two road intersections if packets were successfully delivered from one road intersection to the other in the recent past. To combat against high mobility, in this thesis, we propose a routing protocol based on real-time information on vehicular traffic. We use backup paths for improving the packet delivery ratio in VANETs.
