摘　　要：随着智能终端、平板电脑的普及,用户越来越多地通过Wi-Fi上网。与此同时,人们对视频业务的要求也不断提升,3D等技术给人们带来全新的视觉体验。相对于普通的2D视频,3D视频需要的传输带宽更大,如何在无线网络中提高3D视频的传输质量是一个值得研究的问题。我们提出了一种主动队列管理机制来增强3D视频在无线局域网中的传输质量,在视频业务层需要标识出视频数据的重要性,并将其映射到无线局域网中优先级不同的队列中,保护关键视频数据的传输,提高3D视频的传输质量。With the rapid development of intelligent terminals and tablets, more and more users take on- line through WLAN. The requirement for the video traffic is higher, and 3D technology could bring new visual experience. Compared with the traditional 2D video, it needs more transmission rate to download the 3D video, it＇s a challenge to improve the 3D video transmission in WLAN. In order to resolve this problem, we propose a queue management strategy to improve the 3D Video Transmission in WLAN： the importance of video data is identified, and the video data will be mapped to different queue based on its importance. It could make sure that the important video data is received successfully, and the perform- ance will be enhanced.
