Abstract

VANET (Vehicle Ad-Hoc Network) is an emerging hot technology, but it faces great challenge on quality of service issues since of limited transporting distance and high mobility. To evaluate the quality of video over VANET, a performance evaluation model and a simulation platform VANET-Evalvid is presented in this paper. The tool-set integrates myEvalvid, NS-2 and VanetMobiSim. The performance of different routing protocols under different network conditions is studied. Test results show that Position-based protocol is more suitable than Re-active protocol for video transmission over VANET, whereas Pro-active protocol plays bad performance. Further experiments discover that the quality of video transmitted in dense traffic scenario is better than it in sparse traffic scenario. Comparing with other research, the result testifies the correctness of our model and the efficiency of evaluation platform.
