为了方便的研究无线视频在UWB传输过程中的丢包率、吞吐量、时延，对UWB信道模型进行了研究，使用NS2构建了UWB的网络模型。网络模型配置了模拟网络拓扑结构、各层使用的协议，确定了链路的基本特性，从而可以模拟无线视频传输的UWB环境。构建的网络模型可以模拟压缩编码后视频流的无线传输过程。% In order to facilitate researches of packet loss rate,handling capacity and delay during the UWB⁃based wireless video transmission,the UWB channel model is studied in this paper,and the UWB network model is constructed by using the NS2. Network model adopts the simulative network topological structure and protocols used for each layer. The basic characteris⁃tic of the link is determined. Therefore,the UWB environment for wireless video transmission can be simulated. The network model can simulate wireless transmission process of video streaming after decoding compression.
