摘要

本文对三种著名的ad-hoc路由协议的视频传输性能进行了评价。由于高移动性和快速移动的特点,在自组织网络上传输视频比简单的数据传输变得更加困难。因此,寻找一种有效的多媒体通信方式已成为当今的一个重要问题。我们对两种著名的按需响应路由协议DSR和AODV,以及主动DSDV路由协议进行了全面的比较。我们改进的仿真工具集在本次仿真中与NS-2和myEvalvid-NT一起使用,我们采用了PSNR性能评估指标。结果表明,DSDV在视频传输方面的性能明显差于其他协议,而AODV是我们仿真的最佳路由协议。

Video Transmission Performance Evaluation of Ad Hoc Routing Protocols
This paper evaluates the video transmission performance of three well-known ad-hoc routing protocols. Due to high mobility and rapid movement characteristics, video transmission over ad-hoc networks is becoming more difficult than simple data transmission. Consequently, finding an efficient way for multimedia communication is becoming an important issue nowadays. We make a complete comparison between the two prominent on-demand reactive routing protocols, DSR and AODV, and the proactive DSDV routing protocol. Our improved simulation tool-set is used with NS-2 and myEvalvid-NT in this simulation, and we adopted the PSNR performance evaluation metric. Results indicate that DSDV is much worse than the other protocols for video transmission, and AODV is the best routing protocol in our simulation.
