New Simulation Model for Video Transmissions in VANETs using EVALVID framework

Video transmission and communication in VANETs represents a major challenge because the video streaming in real time will considerably enrich the quality of experience perceived by the user as there will be more visibility on its environment, the conditions of the road traffic, the possibility of using applications such as emergency video calls, etc. However, the transmission of video data in the VANETs is a difficult task since the vehicular networks are a hostile environment for any kind of data especially video transmission (numerous packet losses, mobility of the nodes, etc.), as a result, researchers have focused on improving and optimizing video communication. Unfortunately, evaluating video transmission performance has not been an easy task. Therefore, finding a powerful and an easy tool is fundamental to advancing researches. In this paper, we propose an advanced simulation tool-set which integrates EvalVid framework into NS-2, plus the addition of a mobility file generated from a real life map using SUMO which will make this tool-set credible while measuring delivered videos quality. With the enhancements, the tool-set allows network-related researchers to evaluate real video streams using their proposed network designs or protocols as well as evaluate video quality of their designed video coding mechanisms using a more realistic network.
