随着多媒体技术与通信技术的发展,移动自组网的视频传输越来越重要。路由协议的选择将直接影响网络数据传输的整体表现。我们通过在NS2仿真平台上建立不同的节点运动场景,测试了三种协议OLSR、AODV与DSR在视频通信方面的性能,并对分组投递率、平均帧传输时延与解码端的PSNR三个方面进行了比较与分析。
With the development of multimedia technology and communication technology, mobile ad hoc network video transmission is more and more important. The choice of routing protocol will directly affect the overall performance of network data transmission. We test the performance of the three protocols OLSR, AODV and DSR in video communication by establishing different node motion scenarios on the NS2 simulation platform. We also carry out three aspects of packet delivery rate, average frame transmission delay and PSNR at the decoder side Comparison and analysis.
