Abstract
In Vehicular Ad hoc Networks (VANET), each node can communicate with the other ones in single-hop or multi-hop manner. VANET users require increasingly multimedia services (i.e video streaming) which now represents an important part of the data traffic between those users and the internet. Actually, VANET users tend to pay more attention to Broadband mobile wireless systems for having internet connection to watch video from the internet. Whereas, due to the limited bandwidth to the Internet, users may experience low video resolution and bad transmission quality. In addition, high mobility and dynamic network topology may create an unstable and unreliable communication among VANET users. Thus, guaranteeing quality of service in this kind of communication networks is known to be very challenging. With the objective of providing high-quality video transmission, we propose in this paper, a new multi-segment cooperative forwarding strategy for video streaming for VANET users. The new transmission scheme takes into account the speed of the vehicle, its position (direction) and the distance to the access point. To evaluate the performance of the proposed scheme, extensive simulations are conducted using myEvalvidSVC, NS-2 and VanetMobiSim. Simulation results show that the proposed transmission scheme enables efficient and reliable video transmission over VANETs.
