摘要
分析了机器人远程控制中视频传输的延时问题。提出了一种混合的网络传输拓扑结构,并对传输速率的控制算法进行了移植和改进。利用NS模拟网络环境,在模拟网络中进行数据传输,验证了控制速率算法的可行性。试验结果表明在混合网络拓扑结构上使用控制速率的算法可以减少传输过程中的丢包率,提高视频传输的实时性。
The delay of the real-time video transfer in remote robot control is analyzed, and a hybrid network topology is proposed, and also the control algorithms is improved and, is migrated on transfer rate for enhancing the efficiency. In NS (network simulation) environment, the process of video transfers is simulated. The results validate that hybrid network topology and the rate control algorithm are feasible to decrease packages losing and increase the real-time performance for video transfer in remote robot control.
