摘要：
This paper addresses the problem of real-time video transmission in vehicular networks. We show that the video quality of real-time services is greatly decreased when there is network congestion in different traffic situations. We propose a solution that applies frame skipping and transcoding together with frame rate reduction techniques over IEEE 802.11 based vehicular networks. Our approach improves the quality of video transmission while reducing the bandwidth consumption.
